Abstract

We present a simple framework for image enhancement using local image information. The main idea is to divide the image into small tiles and individually enhance each of these tiles. Enhanced tiles are then mosaicked back together. Our approach is presented for enhancement of fluorescent microscopy images and demonstrates better local contrast preservation and saturation reduction in comparison with traditional global approaches (histogram stretching, equalization or gamma correction).
