An Active Contour Model for Selective Segmentation

In this paper, we develop a new active contour model for image selective segmentation. The model adopts cascade anisotropic diffusion prcprocessing and a selective term in level set function. Cascade anisotropic diffusion filtering is powerful and tlexible to enhance image for various segmentation tasks. The selective term in level set function can evolve a single curve to capture a selective segmentation region which we are interested in. This is useful for intentional segmentatioa tasks. We ,：an al, so realize the multi-region segmentation by varying selecting term conditions. Furthermore, we obviously speed the process of the new algorithm by using AOS scheme in cascade anisotropic diffusion filtering aad discarding mean curvature motiou in level set function. We illustrate the performance of our segmentation method on images generated by different modalities.
