The PDE Method of Image Segmentation

摘要

In this paper, the PDE method of image segmentation was introduced. And then, the geometry active contour was mainly discussed. For example, geodesic active contour (GAC) and active contour without edge (C-V). Furthermore, the application of GAC model in image segmentation and the value achievement of GAC model. At the same time, some corrective methods were summed in this paper. Finally, it got the good result when using C-V model in the detection of spot.
