A novel method for image segmentation is proposed. Considering the segmentation results obtained by using the multiphase Chan-Vese model are dependent on initial conditions, an edge link method is used to obtain initial curve firstly. Based on the Four Color Theorem, we can assume that in general, at most two level set functions are sufficient to detect and represent distinct intensities. Then we...
A novel algorithm for image segmentation is proposed, which combines anisotropic diffusion and Chan-Vese (CV) model to improve contours' performance on multichannel (color, multispectral, hyperspectral, etc) image segmentation. Firstly, the multichannel images are divided into each single channel. Secondly, a novel anisotropic diffusion method is used to smooth the image of each channel. Finally,...
