i am currently doing(going to start) a new project on image comparison method. Basically i want to compare 2 images changed under any circumstances( moustache,beard,inclination etc). I will be going to compare the new image with the database i have and give the closest possible match i get. I request you to help me with this. pls forward me whatever material or research papers you have in relation to this project.I will be very thankful to you.

You could use SSIM : http://en.wikipedia.org/wiki/SSIM "The structural similarity (SSIM) index is a method for measuring the similarity between two images. The SSIM index is a full reference metric, in other words, the measuring of image quality based on an initial uncompressed or distortion-free image as reference. SSIM is designed to improve on traditional methods like peak signal-to-noise ratio (PSNR) and mean squared error (MSE), which have proved to be inconsistent with human eye perception."
or better yet, do some research on CBIR. Just Google "CBIR database"

You could try computing either the mean square error or signal to noise ratio of the two images and see which one gives you the least errors.
