Abstract: To promote the development of the intangible cultural heritage of the world, shadow play, many studies have focused on shadow puppet modeling and interaction. Most of the shadow puppet figures are still imaginary, spread by ancients, or carved and painted by shadow puppet artists, without consideration of real dimensions or the appearance of human bodies. This study proposes an algorithm to transform 3D human models to 2D puppet figures for shadow puppets, including automatic location of feature points, automatic segmentation of 3D models, automatic extraction of 2D contours, automatic clothes matching, and animation. Experiment proves that more realistic and attractive figures and animations of the shadow puppet can be generated in real time with this algorithm.

This paper presents a method to shadowgraph a human 3D model scanned by a 3D laser scanner. It finds the feature points and then segments the various parts of the object. Then with projection planes they get the 2D contours find key points, joints and then map a garment to it. The paper is well written and easy to read and understand. Indeed, the subject of the work is quite original. The paper is worth of interest and of publication.
