— Image denoising is a key issue in all image processing researches. Generally, the quality of an image could be corrupted by a lot of noise due to the undesired conditions of image acquisition phase or during the transmission. Many approaches to image restoration are aimed at removing either Gaussian or impulse noise. Nevertheless, it is possible to find them operating on the same image, which...

We address the arbitrarily varying channel (AVC) with colored Gaussian noise. The work consists of three parts. First, we study general discrete AVC fixed parameters, a model that combines and time-varying channel. determine both deterministic code capacity random capacity. Super-additivity is demonstrated, showing can be strictly larger than weighted sum parametric capacities. In second part, ...
