Is it possible to decompose any image into basis images using MATLAB??

Hello everyone , i have read that any arbitrary image can be represented as summation of othogonal basis images.i want to see the basis images for any image say lena or cameraman.

So can anybody help me to decompose an image into basis imageS and reconstruct back the same image from basis images using MATLAB..???

Thanks in advance..

I got some code from the Mathworks for doing that. Uses principal components analysis. I'll try to remember to post it tomorrow.
