Title: Improving Robot Vision By Color Information

Author:

Subject: Andreas Koschan Improving Robot Vision By Color Information

Description: This paper shows how color information can be utilized to improve the results of dense stereo matching as well as the results of edge-based stereo matching. A hierarchical chromatic Block Matching technique to obtain dense stereo correspondence is presented. The results have been compared to the results of the gray value algorithm. The precision of the matching results always improved by 25 to 30 % when color information instead of gray value information was used. Furthermore, it will be shown how the results of edge-based stereo matching can be improved in quantity and in quality when using color information. This improvement is based on the higher number of edges that can be detected in color images as compared to intensity images. Moreover, the idea of edge classification for edge-based stereo correspondence is outlined. 1 Introduction
