Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0038] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is t...

Abstract

The invention relates to an image processing method and device, computer equipment and a storage medium. The method comprises the following steps: carrying out additional image feature extraction on a training source face image to obtain a source additional image feature; performing identity feature extraction on the training source face image to obtain a source identity feature; inputting the training template face image into an encoder of a face replacement model to obtain face attribute features; inputting the source additional image feature, the source identity feature and the face attribute feature into a decoder of a face replacement model to obtain a decoded face image; obtaining a target model loss value based on an additional image difference between the decoded face image and the comparison face image; and adjusting model parameters of an encoder and a decoder based on the target model loss value to obtain a trained face replacement model. By adopting the method, the face replacement effect can be improved. The image processing method can be based on artificial intelligence, the scheme is applied to the field of video face changing, and the face changing effect can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology and artificial intelligence technology, face-changing technology has emerged. Face-swapping technology refers to changing the face of a person in an image with another face. Face-swapping technology has many application scenarios, such as film and television character production, game character design, virtual image and privacy protection and other scenarios. [0003] At present, face-changing technology can be realized through artificial intelligence-based neural network models. For example, images can be input into the neural network model used for face-changing, and the neural network model can output the image obtained by performing face-changing on the image. [0004] However, there is a large difference bet...
