Using Canny algorithm in QEM simplification for textured 3D models

In this paper, based on edge collapse an improved method of texturing 3D models is promoted, which take the texture into and consideration and make use of Canny algorithm to calculate the borders. We use edge collapse algorithm to simplify the 3D models and the collapse sequence is depended on the collapse cost which combine the edge collapse and the texture collapse. Before simplification, fist using Canny algorithm to calculate the border of the model to keep the basic skeleton of the models.
