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.
OPTIONS
-z zero valued pixels will be ignored in the calculation.
-v verbose mode, useful on short and int images to monitor the
status of the program
