Image segmentation model training method, image segmentation method and device

The invention relates to an image segmentation model training method and device, an image segmentation method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: performing adversarial training on an initial adversarial network based on a sample image pair and a first loss function to obtain an intermediate adversarial network; performing image segmentation on a target image in the sample image pair by adopting an intermediate segmentation model in the intermediate adversarial network to obtain an intermediate segmentation image; determining an edge weight matrix according to edge information in the middle segmentation image; respectively adjusting the first loss function and the middle segmentation image according to the edge weight matrix; performing adversarial training on the intermediate adversarial network according to the sample image pair, the adjusted intermediate segmentation image and the adjusted first loss fu
