Abstract

Correlation methods for polychromatic range image recognition are presented. First, the range and the color are compared and the use of the hue images is discussed. The advantages and disadvantages in combining the range and the color information are analyzed. Single-channel and double-channel approaches are presented. The ability of both recognition methods to be invariant under translation in the xy plane and along the z axis are demonstrated. The codification of the range and the hue images using phase-coding, sine-coding and hybrid coding make possible the fully translation invariance. The double-channel is introduced using sine-coding images in the correlation process. Finally, the combination of those two channels is performed in order to improve the discrimination capability of the system. Digital results are shown.
