Training method and apparatus for image processing model, image processing method and apparatus for image processing model, and storage medium

An image processing method for an image processing model, the method comprising:

• encoding, by an encoder of the image processing model, an original image to obtain a visual feature of a to-be-replaced face in the original image;
• and
• performing, by circuitry of a decoder of the image processing model, decoding based on the visual feature of the to-be-replaced face to obtain a target face having the same visual feature as the to-be-replaced face, wherein
• parameters of the decoder are obtained by performing an update according to a target image comprising the target face without changing parameters of the encoder.

A training apparatus for an image processing model, comprising:

• circuitry configured to update parameters of an encoder in the image processing model according to a to-be-replaced face in an original image, to configure the encoder to encode the to-be-replaced face to obtain a visual feature of the to-be-replaced face;
• update parameters of a decoder in the image processing model according to the to-be-replaced face in the original image, to configure the decoder to perform decoding based on the visual feature of the to-be-replaced face;
• and
• update the parameters of the decoder according to a target face in a target image without changing the parameters of the encoder, to configure the decoder to perform decoding based on the visual feature of the to-be-replaced face and obtain a target face having the same visual feature as the to-be-replaced face.
