Nungsanginla Longkumer, Mukesh Kumar, Rohini Saxena · 2014
Contrast enhancement techniques are used for improving visual quality of low contrast images. Histogram Equalization (HE) method is one such technique used for contrast enhancement. In this paper, various techniques of image enhancement through histogram equalization are overviewed. On comparing them we see that Background Brightness preserving Histogram Equalization (BBPHE) technique provides better and scalable brightness preservation for images with poor contrast.
