Robust color video denoising

A newly reported robust estimation approach for gray-scale image filtering is extended to address the more complex problem of denoising color television signals that have been degraded by weak-signal noise. This new technique differs from previous filtering methods in that it is geared towards the type of color degradations typical of weak-signal television reception, and thus takes into account the physical limitations associated with color signal transmission and the specific types of weak-signal noise generated. Experimental results demonstrating the effectiveness of this new technique are presented at the end of the paper.
