DESCRIPTIONComputes a histogram equalization of an image. The data values of the image are rescaled so that the cumulative histogram of the output image is approximately linear. Each source channel is normalized independently. This operation can be used to enhance the contrast of an image. Histogram equalization is discussed in:
