I'm not exactly what you're doing but take a look at ADAPT_HIST_EQUAL.
From the help:

The ADAPT_HIST_EQUAL function performs adaptive histogram
equalization, a form of automatic image contrast enhancement. The
algorithm is described in Pizer et. al., "Adaptive Histogram
Equalization and its Variations.", Computer Vision, Graphics and Image
Processing, 39:355-368. Adaptive histogram equalization involves
applying contrast enhancement based on the local region surrounding
each pixel. Each pixel is mapped to an intensity proportional to its
rank within the surrounding neighborhood. This method of automatic
contrast enhancement has proven to be broadly applicable to a wide
range of images and to have demonstrated effectiveness.
