Shape Stylized Face Caricatures

Facial caricatures exaggerate key features to emphasize unique structural and personality traits. It is quite a challenge to retain the identity of the original person despite the exaggerations. We find that primitive shapes are well known for representing certain personality traits, in art and psychology literature. Unfortunately, current automated caricature generation techniques ignore the role of primitive shapes in stylization. These methods are limited to emphasizing key distances from a fixed Golden Ratio, or computing the best mapping in a proprietary example set of (real-image, cartoon portrait) pairs. We propose a novel stylization algorithm that allows expressive vector control with primitive shapes. We propose three shape-inspired ideas for caricature generation from input frontal face portraits: 1) Extrapolation in the Golden Ratio and Primitive Shape Spaces; 2) Use of art and psychology stereotype rules; 3) Constrained adaptation to a supplied cartoon mask. We adopt a rec...
