The goal of this workshop is to bring together experts working on applying models, principles, and knowledge of human audio-visual perception and cognition to optimize video processing algorithms and applications. Perceptual and cognitive factors affect how users acquire and process visual information, and an understanding of these factors and experiences offers opportunities to achieve the next big leap in video processing. In particular, many findings from areas such as Vision Science, Behavioral Sciences, and Neuroscience have strong implications for developing efficient, perceptually optimized video processing frameworks, algorithms, and applications. PIVP 2014 welcomes submissions of full papers, as well as short papers reporting work that applies audio-visual perception in video processing. Full papers must be no longer than 6 pages (inclusive of all figures, references, and appendices). Short papers, reporting work-in-progress, are 2 pages, and will be presented as Posters in an interactive setting. Reviews will be double-blind and as such shall not contain any information identifying the author(s) or their organization(s). Papers will be judged on their relevance, technical content and correctness, and the clarity of presentation of the research.
