This paper addresses an approach to robust search based on color images observed in condition of fluctuation in illumination spectrum. A new search method, named 'Color Orientation Code Matching' is proposed, which introduces weighting into the conventional Orientation Code Matching based on monochrome images. The weighting is based on evaluation of stationarity in spectrum in order to avoid mis-matching, under ill-conditions. The experimental results with actual data demonstrate the effectiveness of robust images searching in fluctuation of color spectrum.
