HistNormImg
DESCRIPTION
Computes the histogram normalization of an image.
The data values of the image are rescaled so that the histogram of the
output image is approximately a bell-shaped normal curve with the
desired Mean and Std Deviation. Each source channel is normalized
independently. This operation can be used to enhance the contrast of
an image. Histogram normalization is discussed in:
