Contour Field based Elliptical Shape Prior for the Segment Anything Model
Researchers have developed a new method to enhance the Segment Anything Model (SAM) by incorporating an elliptical shape prior. This approach uses a parameterized elliptical contour field to guide the segmentation process, ensuring that the outputs are elliptical regions. The method decomposes SAM into sub-problems and integrates image features with elliptical and spatial regularization priors, demonstrating improved accuracy on specific image datasets compared to the original SAM.
