A NOVEL APPROACH FOR DENOISING AND ENHANCEMENT OF EXTREMELY LOW-LIGHT VIDEO

Domain: DIP Projects.

A novel approach for noise reduction and enhancement of ext remely low-light video is proposed. For noise removal, a motion adaptive temporal filtering based on a Kalman structured updating is presented. Dynamic range of denoised video is increased by adjustment of RGB histograms using Gamma correction with adaptive clipping thresholds. Finally, residual noise is removed using a nonlocal means (NLM) denoising filter. The proposed method works directly on the color filter array (CFA) raw video for achieving low memory consumption.
