Claim 15:
16. The image segmentation apparatus of claim 15, wherein an input image is the candidate image, the first-level intermediate segmented image, or the second-level intermediate segmented image, wherein an output image is the first-level intermediate segmented image, the second-level intermediate segmented image, or the segmented image, wherein the segmentation network includes an upsampling stage and a downsampling stage, and wherein performing image segmentation on the input image by using the segmentation network comprises:
extracting key features from the input image in the downsampling stage of the segmentation network;
performing multi-scale feature fusion on the key features in the upsampling stage of the segmentation network to obtain a feature map;
performing class prediction on pixel points in the feature map to obtain classes of the pixel points in the feature map; and
marking pixel points of a designated class in the feature map to obtain the output image.
