Abstract

In low light scene, heavy noise deteriorates the quality of captured color images. In this paper, we propose a method for enhancing color images of low light scene using near-infrared (NIR) information. We make use of a single sensor that captures red, green, blue (RGB) and NIR information. Using RGB and NIR information captured by our sensor, we reconstruct clear color images by performing a joint demosaicking and denoisig scheme. Experimental results show the effectiveness of our method.
