Abstract — The paper describes a suitable algorithms pipeline able to enhance the picture quality in terms of both measured and perceived quality. The overall pipeline is mainly devoted to improve image acquired by low cost imaging sensors, typically present in consumer devices (i.e. mobile phone, web-cams, PDA, etc). A series of ad-hoc heuristics and techniques have been applied, taking into account main compression artifacts, chromatic and geometric distortions, etc.. Experimental results show effectiveness of the proposed pipeline.
