In order to overcome the over segmentation phenomenon of edgeflow-driven anistropic diffusion(EAD) and the high computational complexity of(MST) minimum spanning tree,a color image segmentation algorithm based on edgeflow and region merging is presented.First of all,the EAD is applied to the image to get a preliminary result.Then the MST is used to perform the globally optimized region merging.Finally,segmentation results are achieved after proper post-process.Because the MST is based on segment...
