[0020] It can be seen that the embodiments of the present application have the following beneficial effects.

[0021] The embodiments of the present application disclose a method of font generation. When generating a new font, the method includes: obtaining a fifth character providing a font content and a character set providing font attributes, the character set including a sixth character and a seventh character, where a font attribute of the sixth character being different from a font attribute of the seventh character, and a font attribute is configured to characterize a style of a font; inputting the fifth character, the sixth character, and the seventh character into a pretrained font generation network to obtain a target character, a font content of the target character being the font content provided by the fifth character, a font attribute of the target character being determined by the font attribute of the sixth character and the font attribute of the seventh character. That is, the font generation network may extract respective font attributes from the sixth character and the seventh character, and use the two font attributes to generate a new font attribute, and then use the new font attribute to generate the target character. In the present application, since the training samples used when the font generation network is trained include the first character and the second character with different font attributes, the trained font generation network may accurately extract the font attributes of different characters and obtain new font attributes by interpolating different font attributes.

[0029] In order to enable the personnel of this field to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of this application embodiments, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0030] In order to facilitate understanding of the technical solutions provided by the embodiments of this application, the technical terms involved in this application will be explained below.

[0031] Font refers to external formal characteristics of a word, that is, a style of a word. Usually, generation of a font goes through a creative design of a font designer and a stroke-by-stroke design and modification of a font design staff. For example, it includes seal script, clerical script, regular script, cursive script, Song typeface, blackface, etc.

[0032] Currently, a common use is font style conversion, that is, converting one font style into another font style. For example, Generative Adversarial Networks (GAN) is used to achieve style transfer. However, font style conversion may only achieve convertion between existing fonts and may not generate new fonts. The generation of new fonts must rely on designers to spend time and energy, which increases design costs.

[0033] Based on this, embodiments of the present application provide a font generation method. Through training, the font generation network may decouple and encode a font content and a font attribute of a character, and then interpolate attribute encodings of different fonts to obtain new attribute encodings and then generate a new font based on the new attribute encodings and content encodings.

[0034] It should be noted that usually, a font is determined by a plurality of font attributes. A font attribute may include outline, thickness, stroke of a character, etc. Font content refers to a content with the font, i.e., the specific character, for example, “medium” in the font of regular script is considered as having the font content of “medium”.

[0035] Based on the above description, a font generation network training method provided by embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0036] Reference is made to FIG. 1 which is a flow chart of a font generation network training method provided by embodiments of the present application. The initial network model corresponding to the font generation network includes an attribute encoder, a content encoder and a decoder. As shown in FIG. 1, the method may include:

[0037] S101: obtaining training samples including the first character and the second character.

[0038] In the embodiment, in order to make the trained font generation network more accurate, a large number of training samples may be obtained, and the training samples may include the first character and the second character. The first character may provide a font attribute during training, and the second character may provide a font content during training. The font attribute of the first character is different from the font attribute of the second character, and the font content of the first character is also different from the font content of the second character. For example, the first character is “you” in the font of Song typeface, and the second character is “good” in the font of regular script. During training, the first character provides the font attributes of Song typeface, and the second character provides the content of “good”.

[0039] S102: inputting the first character into the attribute encoder to obtain a first attribute encoding, and inputting the second character into the content encoder to obtain a first content encoding.

[0040] After obtaining the training samples, the first character is input into the attribute encoder as an input parameter to obtain the first attribute encoding corresponding to the font of the first character, and the second character is input into the content encoder as an input parameter to obtain the font content of the second character, that is, the second content encoding. The first attribute is encoded as a font attribute feature vector of the first character, which may represent the font of the first character. For example, the first attribute encoding is used to represent that the font of the first character is Songtypeface. The first content encoding is a font content feature vector of the second character, which can represent the specific content of the second character. For example, the first content encoding is used to represent the second character as “good”.

[0041] Optionally, in order to improve a coding accuracy of the content encoder and avoid a loss of strokes during the encoding process, when encoding the second character, the stroke information corresponding to the second character may also be input into the content encoder as an input parameter. Therefore, the first content encoding output by the content encoder may accurately characterize the second character. Specifically, the second character and a stroke encoding corresponding to the second character are input into the content encoder to obtain the first content encoding, the stroke encoding characterizing a radical comprised in the second character.

[0042] A stroke is a smallest unit included in Chinese characters, and each character include several radicals. The stroke encoding is an encoding vector corresponding to a certain word. If it includes a certain radical, the corresponding encoding value is set to 1, otherwise it is set to 0. For example, if there are 32 radicals in total, the strokes are encoded as a 32-dimensional encoding vector.

[0043] S103: inputting the first attribute encoding and the first content encoding into the decoder to obtain a third character.

[0044] After obtaining the first attribute encoding and the first content encoding, they are input into the decoder as input parameters, and the third character is obtained through the decoding operation. The font of the third character output by the decoder is the font of the first character, and the font content is the content of the second character. For example, if the first character is “you” in the font of Song typeface, and the second character is “good” in the font of regular script, then the third character is “good” in the font of Song typeface.

[0045] Optionally, in order to make the font attribute of the generated third character closer to the font attribute of the first character, the first character (attribute word) and the second character (content word) can also be divided into partitions, and each character of the content word can be divided into partitions to find attribute word partitions similar to this partition, so that partition decoding may be performed during decoding. Specifically, character segmentation is performed on the first character and the second character to obtain a plurality of first partitions corresponding to the first character and a plurality of second partitions corresponding to the second character. For any second partition, a first partition that matching the second partition is determined from the plurality of first partitions corresponding to the first character. For any second partition, a content encoding of the second partition and a attribute encoding of the first partition matching the second partition are input into the decoder to obtain the third character. A connected domain segmentation algorithm may be used to segment the first character and the second character. For example, the first character is divided into partition 11, partition 12, and partition 13, and the second character is divided into partition 21, partition 22, partition 23, and partition 24. For the four partitions divided by the second character, the first character is divided into four partitions. Similar partitions are found for each partition of the second character in the three divided partitions, and then the decoder decodes based on the matched pair of partitions, thereby improving decoding accuracy.

[0046] S104: inputting the second character into the attribute encoder to obtain a second attribute encoding, and inputting the third character into the content encoder to obtain a second content encoding.

[0047] In this embodiment, the second character is input into the attribute encoder as an input parameter to obtain the second attribute encoding corresponding to the font of the second character, and the third character is input into the content encoder as an input parameter to obtain the font content of the third character, that is second content encoding. For example, if the second character is “good” in the font of regular script, and the third character is “good” in the font of Song type, then the second attribute encoding is used to characterize that the character attribute of the second character is regular script, and the second content encoding is used to characterize that the font content of the third character is “good”.

[0048] Optionally, when performing content encoding on the third character, the third character and the stroke encoding corresponding to the third character are input into the content encoder to obtain the second content encoding.

[0049] S105: inputting the second attribute encoding and the second content encoding into the decoder to obtain a fourth character.

[0050] The second attribute encoding corresponding to the second character and the second content encoding corresponding to the third character are input into the decoder as input parameters, and the fourth character is obtained through the decoding operation. That is, the original content word is reconstructed by using the generated word (the third character) as the content word and the original content word (the second character) as the attribute word. For example, if the first character is “you” in the font of Song type and the second character is “good” in the font of regular script style, then the generated character is the third character, i.e., “good” in the font of Song typeface, and the reconstructed fourth character is “good” in the font of regular script.

[0051] S106: adjusting the parameters of the initial network model based on the font attribute of the first character and a font attribute of the third character.

[0052] After the fourth character is obtained, the parameters of the initial network model are adjusted based on the difference between the font content of the second character and the font content of the fourth character. Specifically, parameters of the content encoder in the initial network model are adjusted based on the font content of the second character and the font content of the fourth character to improve the coding accuracy of the content encoder.

[0053] Optionally, the second character and the fourth character are input into a first discriminator, and the parameters of the initial network model are adjusted based on a discrimination result of the first discriminator, the first discriminator being configured to discriminate a difference between the font content of the second character and the font content of the fourth character. A discriminant loss function may be obtained through the first discriminator, and the discriminant loss function is used to adjust the parameters of the initial network model.

[0054] Optionally, in order to further improve the coding accuracy of the content encoder, the parameters of the initial network model may also be adjusted based on the difference between the stroke ecoding corresponding to the third character and the stroke ecoding corresponding to the second character. Specifically, the third character is input into the stroke classifier to obtain the first stroke encoding; the parameters of the initial network model are adjusted according to the first stroke encoding and the second stroke encoding corresponding to the second character. For example, the first stroke encoding and the second stroke encoding are input into the third discriminator, and the parameters of the content encoder are adjusted according to the discrimination result of the third discriminator. The third discriminator is used to identify the difference between the first stroke encoding and the second stroke encoding.

[0055] S107: adjusting the parameters of the initial network model based on the font attribute of the first character and a font attribute of the third character, and repeating the above training process until a predetermined condition is satisfied, to obtain the font generation network.

[0056] In the embodiment, the parameters of the initial network model are adjusted by using the difference between the font attributes of the first character and the font attributes of the third character. Specifically, the parameters of the attribute encoder in the initial network model are adjusted based on the font attributes of the first character and the font attributes of the third character to improve the coding accuracy of the attribute encoder.

[0057] Optionally, the first character and the third character are input into a second discriminator, and the parameters of the initial network model are adjusted based on a discrimination result of the second discriminator, the second discriminator being configured to discriminate difference between the font attribute of the second character and the font attribute of the fourth character, and the discrimination loss function is obtained through the second discriminator, so as to use the discrimination loss function to adjust the parameters of the attribute encoder.

[0058] After adjusting the parameters of the initial network model based on S106 and S107, the training processes of S102 to S107 are re-executed until the predetermined conditions are met, and the font generation network is obtained. The predetermined condition may be set according to an actual situation, for example, the discrimination loss function of the first discriminator is less than the first predetermined threshold and/or the discrimination loss function of the second discriminator is less than the second predetermined threshold, etc.

[0059] It should be noted that an execution order of S106 and S107 in this embodiment is not limited by the above. S107 may also be executed first and then S106, or S106 and S107 can be executed at the same time. The execution order of S107 and S104-S106 is not limited to the above. S107 may be executed first, and then S104-S106 may be executed, or S107 and S104-S106 may be executed at the same time.

[0060] It can be seen that when training the font generation network, training samples including a first character and a second character are obtained, the first character is used to provide font attributes, and the second character is used to provide font content. The first character is input into the attribute encoder of the initial network model to obtain the first attribute encoding, and the second character is input into the content encoder of the initial network model to obtain the first content encoding. The first attribute encoding and the first content encoding are input into the decoder of the initial network model to obtain the third character. The third character is input into the content encoder to obtain the second content encoding, and the second character is input into the attribute encoder to obtain the second attribute encoding. The second attribute encoding and the second content encoding are input into the decoder to obtain the fourth character. The parameters of the initial network model are adjusted based on the font content of the second character and the font content of the fourth character, and the parameters of the initial network model are adjusted based on the font attributes of the first character and the font attributes of the third character. After adjustment, the above training processes are re-executed until the predetermined jump instructions are satisfied and the font generation network is obtained. The parameters of the initial network model are adjusted based on the font content of the second character and the font content of the fourth character, the content encoder is mainly adjusted, so that the content encoder may accurately encode the content of the input character. Based on the font attributes of the first character and the font attributes of the third character, the parameters of the initial network model are mainly adjusted to adjust the attribute encoder so that the attribute encoder may input the attributes of the character for accurate encoding. Through the above training, the attribute encoder and content encoder are decoupled.

[0061] Referring to the initial network model architecture diagram shown in FIG. 2, the initial network model includes an attribute encoder, a content encoder, a decoder, a first discriminator and a second discriminator. The first character is inputted into the attribute encoder to obtain the first attribute encoding, and the second character and stroke encodings are input into the content encoder to obtain the first content encoding. The decoder performs a decoding operation on the first attribute encoding and the first content encoding to obtain the third character.

[0062] Then the second character is inputted into the attribute encoder to obtain the second attribute encoding, and the third character and stroke encoding are inputted into the content encoder to obtain the second content encoding. The decoder performs a decoding operation based on the second attribute encoding and the second content encoding to obtain the fourth character.

[0063] The first and third characters are fed into the second discriminator and the obtained loss is fed back to the attribute encoder. The second character and the fourth character are input to the first discriminator and the obtained loss is fed back to the content encoder.

[0064] Based on the font generation network generated by the above training, this font generation network will be used to generate new fonts.

[0065] Reference is made to FIG. 3 which is a flow chart of a font generation method provided by embodiments of the present application. As shown in FIG. 3, the method may include:

[0066] S301: obtaining a fifth character providing a font content and a character set providing font attributes, the character set comprising a sixth character and a seventh character, a font attribute of the sixth character being different from a font attribute of the seventh character, and a font attribute is configured to characterize a style of a font.

[0067] In the embodiments, in order to obtain new fonts, the fifth character and the character set are obtained. The fifth character is used to provide font content, and the characters in the character set are used to provide font attributes. The character set may include a plurality of characters with different font attributes, and the font attributes may characterize a style of a font.

[0068] S302: inputting the fifth character, the sixth character, and the seventh character into a font generation network to obtain a target character.

[0069] After obtaining the fifth character providing font content and the sixth and seventh characters providing font attributes, the above characters are input into the font generation network to obtain the target character through the font generation network. The font content of the target character is the font content provided by the fifth character, the font attribute of the target character is determined by the font attribute of the sixth character and the font attribute of the seventh character, and the font attribute of the target character are different from the font attribute of the sixth character and the font attribute of the seventh character.

[0070] From the above, it can be seen that the font generation network may include an attribute encoder and a content encoder. After obtaining the fifth, sixth, and seventh characters, the font generation network may use the attribute encoder and the content encoder to encode the above characters, respectively. Processing may include the following steps:

• • [0071] 1): The sixth character and the seventh character are input into the attribute encoder of the font generation network to obtain the sixth attribute encoding and the seventh attribute encoding, respectively.
  • [0072] 2): The sixth attribute encoding and the seventh attribute encoding are mixed to obtain the target attribute encoding.

[0073] In this embodiment, the sixth character and seventh character providing font attributes are input into the attribute encoder of the font generation network to obtain the sixth attribute encoding corresponding to the first character and the seventh attribute encoding corresponding to the seventh character. Then, the target attribute encoding is obtained by mixing the sixth attribute encoding and the seventh attribute encoding, and the target attribute encoding is used to characterize the new font attribute. Specifically, the sixth attribute encoding and the seventh attribute encoding are input into the mixer of the font generation network to obtain the target attribute encoding. The mixer may mix the sixth attribute encoding and the seventh attribute encoding in a weighted manner to obtain the target attribute encoding.

• • [0074] 3): The fifth character is input into the content encoder of the font generation network to obtain the target content encoding.

[0075] Optionally, when obtaining the content encoding corresponding to the fifth character, the fifth character and the stroke encoding corresponding to the fifth character may be input into the content encoder, so that the target content encoding output by the content encoder is more accurate.

• • [0076] 4): The target attribute encoding and the target content encoding are inputted into the decoder of the font generation network to obtain the target character.

[0077] When the decoder decodes the target attribute encoding and the target content encoding to generate the target characters, it can use the SPADE method to decode to strengthen the intensity of the target attribute encoding and make the font attributes of the generated target characters more significant.

[0078] It can be seen that after the attribute encoder and content encoder in the font generation network are decoupled, the attribute encoder may be used to extract the attribute encoding of the sixth character and the attribute encoding of the seventh character, and obtain new target attributes through interpolation. The new target attribute encoding represents the new font. After decoding the target attribute encoding and the target content encoding, the new font is obtained.

[0079] Referring to the scene graph shown in FIG. 4, the font generation network includes an attribute encoder, a content encoder, a decoder and a mixer. The fifth character and the stroke encoding are input into the content encoder to obtain the target content encoding, and the sixth character and the seventh character are input into the attribute encoding to obtain the sixth attribute encoding and the seventh attribute encoding, and the target attribute encoding is obtained through the mixer. The decoder obtains the target word character by decoding the target content encoding and the target attribute encoding.
