A Single Image Enhancement using Inter-channel Correlation

A single image enhancement algorithm using inter-color channel relationship is presented. It is based on the fact that the property of an infrared range image is similar to that of red channel in a visible range color image. Specifically, the proposed method analyzes the image details, which are mostly resided in dark area and not visible well in the visible range image, directly from the red channel of the given image. And they are used as a guidance to generate a weighting map for image enhancement. Experiment results show that the proposed scheme produces good outcomes in terms of revealing dark region details and visually pleasant observation.
