If a colour image is converted to gray scale then significant features are sometimes removed (i.e. two coloured objects with the same brightness will look the same in gray scale). This project will investigate approaches for overcoming this. See Gooch et al.'s "color2gray" system on the web for more details. In addition, if time permits, a similar approach will by applied to modify the hue in colour images, which should generate artistic images in a "Fauvist" style.
