PIXSTAT(1)			    BRL-CAD			    PIXSTAT(1)

NAME
       pixstat - list statistics related to a color pix	image

SYNOPSIS
       pixstat [-v] [file.pix]

DESCRIPTION
       pixstat will take the given pix(5) format file, or read from standard
       in. A collection	of statistics related to the pixel intensities is
       produced	for each color plane (red, green, and blue).  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 (each color	having 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.
