BWSTAT(1)			    BRL-CAD			     BWSTAT(1)

NAME
       bwstat -	list statistics	related	to a black and white bw	image.

SYNOPSIS
       bwstat [-v] [file.bw]

DESCRIPTION
       Bwstat will take	the given bw(5)	format file, or	read from standard in.
       A collection of statistics related to the pixel intensities is
       produced.  These	include: The number of pixels (and the square root of
       this which is the file dimensions if square).  The max and min values.
       The mean.  The median (dividing line where half the pixels are above
       this value, half	below).	 The mode (most	frequently occurring value)
       and the number of pixels	at this	value.	The variance, standard
       deviation, and skew.

       The -v flag will	also dump a histogram of the pixel values.

METHOD
       Since the pixel values are quantized (have discrete values from 0 to
       255), the statistics can	be computed from "lump sums" after building a
       histogram of the	input. This results in a fantastic savings in
       computation while also making a single pass over	the input file
       sufficient.
