This paper presents an overview of state-of-the-art technologies for perceptual processing of digital pictures, as well as a discussion of the issues related to their implementation, optimization and testing. The paper begins with a brief description of the main computational modules that are used as part of a perceptual-based visual signal processing framework. Then, a number of perceptual-based visual processing techniques and applications to which perceptual models are presented, including image/video compression, visual signal quality evaluation, and computer graphics. The most significant research efforts are highlighted for each topic, and a number of issues and views are put forward regarding the related research and opportunities.
