NAME

histoeq2 - histogram equalization (handles short images)  

SYNOPSIS

histoeq2 [-z] [-v]  

DESCRIPTION

Histoeq2 performs histogram equalization on byte-formatted images. It performs a variant of the Peleg algorithm, shuffling around pixels in order to best approximate a ramp cumulative distribution of pixel values. This program with accept byte, short, and int image. However, with short and int images, the histogram is scaled to 1500 buckets, and the histogram equalization produces only 1500 different gray values.
