Hi. I'm not sure of which filter to use. Could someone help me by explaining which filter I should use? I need to show the digits from the digital display in the image.

There are some filters that may work, such as mean shift, anisotropic diffusion ( http://www.csse.uwa.edu.au/~pk/Research/MatlabFns/#anisodiff), or bilateral ( http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/MANDUCHI1/Bilateral_Filtering.html) You may also want to investigate noise reduction methods like non-local means and BM3D. However, your most promising solution right now is simply to get a better image. Get proper lighting and alignment of your camera. That is your biggest problem at the moment, and everyone knows it is so much easier to get good images to start with than to try to fix up poor quality images after they've been captured.

I don't know. If you got it from Peter's web site - the link I gave - then I guess it must be. Of course you may need to be adapt it slightly to your situation, but I've done it and it works for my images.
