I am looking for an image comparison algorithm. I need to compare two RGB
images (24 bits per pixel) considering a mismatch percent. If the first image is
lighter than the secound one them they has to be consider as equal images.
Can anyone help me?

Try this. Convert to freq domain. Throw away DC.
Compare only AC coefs.
Or remove mean from both the images. If required,
normalise using standard deviation of the 2 images.
And compare in pixel domain.
