Embodiment Construction
[0010] This specific implementation adopts the following technical scheme: it expresses the level set function in a space-time discrete grid, first constructs the SDF function, initializes it to zero, solves the numerical solution of the partial differential equation, and finally passes the signed distance function of the curve Re-initialize, and determine whether the value is stable, if yes, stop the iteration, otherwise repeat the above process.
[0011] This specific implementation uses a new variational level set model based on the CV model, which combines the edge and area information of the image; for the external energy item, on the basis of retaining the original CV model energy item, Adding the gradient value of the image before and after the segmentation, a new model function can be obtained.
[0012] This specific implementation has a better localization effect on the image boundary, and combines the image edge and area information to improve the clarity and disting...
