Decolorization: is rgb2gray() out?

Decolorization -- the process to transform a color image to a grayscale one -- is a basic tool in digital printing, stylized black-and-white photography, and in many single channel image and video processing applications. While recent research focuses on retaining meaningful visual features and color contrast, less attention has been paid to the complexity issue of the conversion. Consequently, the resulting decolorization methods could be orders of magnitude slower than simple procedures, e.g., Matlab built-in rgb2gray function, which could hamper them from being used practically. In this paper, we propose a very fast and yet effective decolorization approach. The effectiveness of the method is borne out by a new quantitative metric as well as qualitative comparisons with state-of-the-art methods.
