Hello,

how can I decide that an image is symmetric or asymmetric in color after dividing it into two parts vertically (the right part and the left part)? thanks

You could chop the image in half, call fliplr() to flip one of the halves, then check similarity with SSIM (See wikipedia) or something similar like PSNR.

There is an ssim() function in the Image Processing Toolbox. Or you cuold look for published articles on it here: http://www.visionbib.com/bibliography/contents.html

I haven't ssim() function in MATLAB 2013. Can you tell me some other method to implement this in Matlab

I did , sort of - did you see the link I gave you? That will have the best methods by people who have studied it intensively. Maybe my guess of SSIM is not even the best way.

If you still want ssim(), upgrade to the latest version of MATLAB, or program it yourself with information from http://en.wikipedia.org/wiki/Structural_similarity
