OPERATOR
equalize --- equalize an image
DESCRIPTION
The equalize operator enhances image contrast by increasing dynamic range. Pixel
values less than lo are mapped to minimum pixel value, and pixel values
greater than hi are mapped to the largest pixel value. Actual min/max value
depends on image type, e.g. 8-bit unsigned images would have a minimum pixel
value of 0, and a maximum of 255. Pixel values between lo and hi are
stretched linearly to span the range from minimum to maximum pixel value.
