Noise removal on color image sequences using coupled anisotropic diffusions and noise-robust motion detection

Abstract

In this paper, we propose a new approach for noise removal on color image sequences, based on coupled spatial and temporal anisotropic diffusions. This approach consists in smoothing a sequence while keeping all discontinuities caused by edges and moving objects. Our approach is based on a low level detection of moving areas in a noisy sequence, in order to associate temporal diffusion to a spatial diffusion process, thus denoising the sequence more efficiently.
