NAME

bwhisteq - equalize the histogram of a black and white bw file

SYNOPSIS

bwhisteq [-v] file.bw > file.equalized

DESCRIPTION

bwhisteq automatically equalizes the histogram of a black and white bw(5) format file. It reads the file file.bw and writes a "remapped" version of it on standard output. The method used is to distribute the values of the histogram, as best as possible, in order to produce a constant average "density", while maintaining monotonicity.

The -v flag will output the old and new histogram values on the terminal.
