Abstract

The present application discloses a model training method and apparatus, and a biometric image generation method and apparatus. The model training method comprises: acquiring a first sample image, sample distribution data, a second sample image, and a first preset signal; inputting into a generation model to be trained a first encoded feature of the first sample image and the sample distribution data for biometric image generation processing to obtain a target sample image; by incorporating a first object recognition result corresponding to the first sample image, a second object recognition result corresponding to the second sample image, and a third object recognition result corresponding to the target sample image, determining a comparison recognition loss; determining a biological texture loss on the basis of the first encoded feature and the first preset signal; and training said generation model on the basis of the comparison recognition loss and the biological texture loss to obtain an image generation model. The present application can improve the performance of the image generation model, thereby improving the biometric image generation effect by means of the image generation model.
