In this paper, we present an algorithm for visualizing edges in RGB colored images as well as edge detection using logarithmic ratio approach. The developed visualization algorithm has a superior performance in highlighting more unforeseen color edges than the standard RGB-grayscale conversion method can present. Also, by integrating the proposed algorithm with a logarithmic-ratio based edge detector operator, the developed algorithm outperforms the standard edge detection operators in gradient colored images where color boundaries transitions are hard to detect.
