perhist - print percent histogram values for an image
perhist
inimage [minpercent maxpercent] [-3]
perhist analyzes the histogram
of an image and prints two pixel values. 1 percent of the pixels in the
image will less than the first pixel value printed, while 99 percent of
the pixels will be less than the second value printed. These two pixel values
can be used as arguments to [lq]imgexp[rq] to increase the contrast of
an image with out loosing too much detail in the shadows or the highlights.
The default min percent and max percent values are 1 perecnt and 99 percent
by default, but these values can be changed by specifying them on the command
line. The [lq]-3[rq] option causes the percent histogram values to be printed
independently for each channel of a color image.
