  • Patent number: 10482604
    Abstract: A method for image segmentation may include acquiring an image including a region of interest (ROI). The ROI has a first margin, the ROI includes a subregion, and the subregion has a second margin. The method may further include acquiring a first model according to the ROI, wherein the first model has a third margin. The method may further determine, based on the first margin and the third margin, a second model by matching the first model with the image, wherein the second model includes a sub-model, and the sub-model has a fourth margin. The method may further include determining, based on the second margin, a third model by adjusting the fourth margin of the sub-model in the second model. The method may further include segmenting the ROI according to the third model and generating a segmented ROI based on a result of the segmentation.
