Brightness preserving contrast enhancement in digital pathology

Majority of images in digital pathology require post acquisition adjustments to optimize brightness, contrast, and image visibility. Despite this fact much research effort has not been put in development of customized contrast enhancement techniques for this application. In this respect various contrast enhancement techniques developed for other application areas can be customized for the digital pathology. This paper proposes use of a brightness preserving contrast enhancement technique for image enhancement in digital pathology applications and compares its functional superiority over other contemporary techniques.
