A Generation Algorithm of Caricature Portrait

This paper introduces a new facial caricaturing method for 2D cartoon portraits with exaggeration to simulate the works of the artists.By the method,firstly,a photo of front face inputs and its characteristic points are specified by users.According to the characteristic values calculated based on the characteristic points,the proper parts of the face demanding deformation and their respective ways of exaggeration are decided.Then the mesh models of different layers are automatically generated based on the characteristic points and exaggerative deformations are carried out layer by layer.At last,the image is manipulated to get different styles.The study of the arithmetic starts from the research on the styles of the artist works,and summarizes the exaggeration rules of cartoon portraits.This approach can help generate relatively good cartoon portraits and can be used in unrealistic computer graphics and digital entertainment.
