MATLAB has the adapthisteq() function in the Image Processing Toolbox. You can get more precise than that if you want, by sorting, adding sub-graylevel noise, etc.. Search sci.image.processing for discussions on it. If you want to do color histogram matching (make a color image match colors in a second color image), then the best I've seen is detailed here: http://www.cl.cam.ac.uk/~mg290/Portfolio/ColorHistogramWarp.html
