Application of ID FIR filter methods to 3D polygonal meshes

摘要

This paper discusses a procedure of filtering a three dimensional (3-D) polygonal mesh by utilizing the basic methods of finite impulse response (FIR), one dimensional (1-D) filtering. A method of linearizing a 3-D mesh was developed in order to apply the 1-D filter methods. With the development of low cost 3-D scanners, which physically scan and digitize real-world objects, the amount of "noise" that is found on these models has increased. This noise can come from various sources, including unwanted imperfections in the object itself, and from the device being used to scan the object. This newly developed filtering method will provide not only a way to decrease the noise in models, but increase details of the model as well, using low-pass and high-pass filters respectively.
