Claim 0:
1. An image segmentation method, applicable to a computer device, the method comprising:
obtaining a current frame and historical affine transformation information of a previous video frame in a video frame sequence, wherein the historical affine transformation information of the previous video frame includes parameters obtained from an image segmentation processing of the previous video frame and revised for affine transformation of the current frame;
performing the affine transformation on the current frame according to the historical affine transformation information to obtain a candidate region image corresponding to the current frame;
performing feature extraction on the candidate region image to obtain a feature map corresponding to the candidate region image;
performing semantic segmentation based on the feature map to obtain a segmentation result corresponding to a target in the current frame; and
revising the historical affine transformation information according to the feature map to obtain updated affine transformation information, and using the updated affine transformation information as historical affine transformation information corresponding to a subsequent video frame in the video frame sequence.
