BWHISTEQ 1 BRL-CAD BRL-CAD
bwhisteq equalize the histogram of a black and white bw file
`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.
