There are efforts to produce caricatures mechanically or semi-automatically mistreatment computer graphics techniques. as an example, a system projected by Akleman et al.[13] provides warping tools specifically designed toward apace manufacturing caricatures. There square measure very few package programs designed specifically for automatically making caricatures.
