Detection of human skin in an arbitrary image is generally hard. Most color-based skin detection algorithms are based on a static color model of the skin. However, a static model c...

We investigate the general problem of reproducing color images on an offset press using custom inks in any combination and number. While this problem has been explored previously ...
