Method and apparatus for generating cartoon face image, and computer storage medium

An apparatus for generating a cartoon face image, comprising:

• circuitry configured to:
• obtain a to-be-processed face image;
• recognize face feature information from the to-be-processed image including coordinates of key location points;
• separately obtain each of different cartoon feature parts of a face in the to-be-processed image according to the face feature information, the cartoon feature parts being obtained independently of facial contour information of the face in the to-be-processed face image, the cartoon feature parts including cartoon facial parts and another cartoon material other than the cartoon facial parts;
• separately adjust each of the cartoon facial parts by using an adjustment parameter corresponding to the respective cartoon facial part, the adjustment parameter corresponding to the respective cartoon facial part including at least one of an offset ratio or a scaling ratio based on one or more of the coordinates of the key location points of the face feature information from the to-be-processed face image and based on one or more coordinates of key location points of a preset standard face image, such that an offset ratio or a scaling ratio of a first cartoon facial part is different from an offset ratio or a scaling ratio of a second cartoon facial part with respect to standard cartoon facial feature parts corresponding respectively to the first cartoon facial part and the second cartoon facial part;
• and
• combine the other cartoon material with the adjusted cartoon facial parts to generate the cartoon face image,
• wherein the scaling ratio is obtained according to a first ratio and a second ratio, the first ratio being a ratio of a first dimension of a first facial part in the to-be-processed face image to a second dimension of a second facial part in the to-be-processed face image and the second ratio being a ratio of the first dimension of the first facial part in the preset standard face image to the second dimension of the second facial part in the preset standard face image, and
• wherein the offset ratio is a ratio of a first distance ratio of facial parts of the to-be-processed face image to a second distance ratio of the facial parts of the standard face image, the first distance ratio being a ratio of a distance between the facial parts in the to-be-processed face image to a width of a face shape of the to-be-processed face image and the second distance ratio being a ratio of a distance between the facial parts in the standard face image to a width of a face shape of the standard face image.

A non-transitory computer-readable medium storing computer-readable instructions thereon that, when executed by a processor, cause the processor to perform a method, comprising:

• obtaining a to-be-processed face image;
• recognizing face feature information from the to-be-processed face image including coordinates of key location points;
• separately obtaining each of different cartoon feature parts of a face in the to-be-processed face image according to the face feature information, the cartoon feature parts being obtained independently of facial contour information of the face in the to-be-processed face image, the cartoon feature parts including cartoon facial parts and another cartoon material other than the cartoon facial parts;
• separately adjusting each of the cartoon facial parts by using an adjustment parameter corresponding to the respective cartoon facial part, the adjustment parameter corresponding to the respective cartoon facial part including at least one of an offset ratio or a scaling ratio based on one or more of the coordinates of the key location points of the face feature information from the to-be-processed face image and based on one or more coordinates of key location points of a preset standard face image, such that an offset ratio or a scaling ratio of a first cartoon facial part is different from an offset ratio or a scaling ratio of a second cartoon facial part with respect to standard cartoon facial feature parts corresponding respectively to the first cartoon facial part and the second cartoon facial part;
• and
• combining the other cartoon material with the cartoon facial parts after adjustment to generate a cartoon face image,
• wherein the scaling ratio is obtained according to a first ratio and a second ratio, the first ratio being a ratio of a first dimension of a first facial part in the to-be-processed face image to a second dimension of a second facial part in the to-be-processed face image and the second ratio being a ratio of the first dimension of the first facial part in the preset standard face image to the second dimension of the second facial part in the preset standard face image, and
• wherein the offset ratio is a ratio of a first distance ratio of facial parts of the to-be-processed face image to a second distance ratio of the facial parts of the standard face image, the first distance ratio being a ratio of a distance between the facial parts in the to-be-processed face image to a width of a face shape of the to-be-processed face image and the second distance ratio being a ratio of a distance between the facial parts in the standard face image to a width of a face shape of the standard face image.
