matlab code of ssim of image quality

the above codes are very useful for image segmentation,edge detection

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.

need matlab codes which shows the segmentation of the image in boundries. and showing the limitations of image.
