autoEqualize --- automatically equalize an image
DESCRIPTION
The autoEqualize operator performs automatic image contrast enhancement by
computing an equalization interval based on the input integer image intensity
frequency distribution. The interval is determined by searching the image
histogram from both extremes such that two extrema are found which represent
more than a certain percentage of the total image area. The percentage is
controlled through the fraction parameter. Allowable range is 0-100.
