Method Detail

processImage

public void processImage(FImage image)

Equalise the colours in the image. Creates a histogram that contains as many bins as colours, equalises it, then back-projects it into an image. The resulting image has equalised values between 0 and 1. It assumes the image has already been normalised such that its values are also between 0 and 1. It is assumed that there are 256 discrete grey-levels.

Specified by:

processImage in interface ImageProcessor<FImage>

Parameters:

image - The image to process in place.
