Not really. That would be almost as broad as asking "Can anyone here explain physics and math to me?" Why don't you try Googling the web for a while and come back and ask specific questions, like "Is there a function to do non-linear filtering of an image in MATLAB?" (Yes there is, it's called nlfilter). Or "Is there a way to generate random numbers from a normal distribution?" (Yes, use randn).
