In general no preprocessing required to extract SURF. Lightning is normalized inside build of surf descriptors. Perpixel noise is not important , cause SURF use big enough processing windows. SURF itself designed to be robust to some extrinsic noises.

Are there any recommended pre-processing steps to perform before extracting SURF features from an image? For example, lighting / color balance, histogram equalization, etc.?
