TopHat Contrast Enhancement

API


This class enhances the contrast by top-hat operations, especially for gray value bright filed or DIC images. A white top-hat is added to the original image (enhance bright objects) and subsequent a black top-hat is subtracted (enhance dark objects).

This approach works well for DIC images, maybe also for bright field or other illumination/contrast based images. Mask size of the structuring element should be small to preserve small structures, like neurites.

NOTE: maybe the result image must be re-scaled, since output gray values can fall outside the dynamic range of the input image!

The approach is adapted from:
