| titleOfInvention | A Segmentation Method Based on Shape Preserving Convexity Level Set Model |
| abstract | A segmentation method based on the shape-preserving convexity level set model firstly obtains the image to be segmented, performs rough segmentation on the image to be segmented to obtain a binary image, and then uses the binary image to construct an initial level set function and accurately segment the target boundary. The invention proposes to extract the boundary by using the shape-preserving convexity level set model, which can ensure that the level set curve maintains the convexity in the iterative evolution process of the level set function, and uses the constructed evolution formula to iteratively update the level set function and extract the 0 level set to obtain the boundary By dividing the curve, the constructed evolution equation can avoid the leakage of the curve boundary during the curve evolution process, and has the tendency to maintain the area; for the target object of the double-layer boundary, the invention also converts the evolution formula to construct the evolution formula of the double level set function , using the evolution formula of the double level set function to iteratively update the level set function and extract the 0 level set and the k level set to obtain two boundary segmentation curves inside and outside. |
