This program was written as a part of the d-deDUMedical Imagingd-deDt course. Together with Alex Blekhman (http://www.mathworks.com/matlabcentral/fil...e/authors/26540)- my partner we have implemented the paper "Active Contours without Edges" by Tony Chan and Luminita Vese. We wrapped it up with...

The code has been tested successfully on a number of images. The algorithm is based on paper tiled "Accurate eye center location using isophote curature" presented by Roberto valenti and Theo Gevers at CVPR 2008 in ALASKA.

An implementation of [1], it works in follows:1. Compute the Jmap.2. Compute the valleys of Jmap.3. Valleys growing as the oversegmentation.4. Region merging.Example usage:%labels = colorImgSeg('imagessflowg.jpg', 12, 5, 10,0.35, 0.02, 0.88);To run the code, you have to firstly generate the...
