Title:	3-D Signal Processing in a Computer Vision System
Author(s):	Zhu, Dongping; Conners, Richard W.; Araman, Philip A.
Date:	1991
Source:	Proceedings, IEEE International Conference on Systems Engineering. pp. 457-460.
Description:	This paper discusses the problem of 3-dimensional image filtering in a computer vision system that would locate and identify internal structural failure. In particular, a 2-dimensional adaptive filter proposed by Unser has been extended to 3-dimension. In conjunction with segmentation and labeling, the new filter has been used in the computer vision system to successfully detect potential wood defects.
