IMAGE SEGMENTATION METHOD AND APPARATUS, DEVICE, AND READABLE STORAGE MEDIUM

WIPO Patent Application WO/2024/055446

A1

The present application belongs to the field of image processing. Disclosed are an image segmentation method and apparatus, a device, and a readable storage medium. The method comprises: acquiring an initial segmentation image and an original image to be segmented comprising a target object, and inputting into an active contour model the initial segmentation image and said original image to perform image segmentation, so as to obtain a target segmentation image. A target energy functional used by the active contour model comprises a fidelity term carrying a constant weighting coefficient, a length term carrying a first adaptive weighting coefficient and a smooth term carrying a second adaptive weighting coefficient, the first adaptive weighting coefficient and the second adaptive weighting coefficient being determined by means of said original image. Thus, when an image to be segmented is segmented by means of the active contour model, the weighting coefficients of the length term and the smooth term of the target energy functional of the active contour model can be correspondingly adjusted according to different images to be segmented, thereby improving the robustness and the image segmentation precision of the active contour model.
