Abstract. This paper presents a computer-aided approach to enhancing
suspicious lesions in digital mammograms. The developed algorithm improves
on a well-known preprocessor filter named contrast-limited adaptive histogram
equalization (CLAHE) to remove noise and intensity inhomogeneities. The
proposed preprocessing filter, called fuzzy contrast-limited adaptive histogram
equalization (FCLAHE), performs non-linear enhancement. The filter
eliminates noise and intensity inhomogeneities in the background while
