Abstract

The invention provides a training method of a face change identification model, a face change identification method, device and equipment, belongs to the technical field of computers, and relates to artificial intelligence and computer vision technologies. When the face-changing identification model is trained, the non-face-changing face sample image and the face-changing face sample image of thesame sample object are included in one sample image group, the face-changing identification model is trained, and the parameters of the face-changing identification model are adjusted based on the loss value generated by the model for the sample image group. The face main feature difference between the non-face-changing face sample image and the face-changing face sample image of the same sample object is very small; therefore, the model can adjust the parameters; learning of main features of the face of the image is weakened, more attention is paid to the difference features of the face sample image without face changing and the face sample image with face changing, shaking of the model in the training process can be reduced, the convergence speed of the model is increased, and the identification accuracy of the face changing identification model during identification of the face image is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a training method of a face-changing identification model, a face-changing identification method, device and equipment. Background technique [0002] Face recognition technology can identify identity by analyzing and comparing facial visual feature information. With the continuous improvement of face recognition technology, face recognition technology has been widely used in many fields. [0003] At the same time, with the continuous development of image processing technology, the face area in the image can be processed by drawing tools or other image processing methods, and the face of the first object can be replaced by the face of the second object. For example, the faces of two people in an image or video can be swapped using Deepfake face-changing technology. The processed images of faces have posed new challenges for facial recognition technology and c...
