16. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement
Abstract : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. READ MORE

17. Interpolation Techniques with Applications in Video Coding
Abstract : Recent years have seen the advent of RGB+D video (color+depth video), which enables new applications like free-viewpoint video, 3D and virtual reality. This is however achieved by adding additional data, thus increasing the bitrate. READ MORE

19. Sparse representation of visual data for compression and compressed sensing
Abstract : The ongoing advances in computational photography have introduced a range of new imaging techniques for capturing multidimensional visual data such as light fields, BRDFs, BTFs, and more. A key challenge inherent to such imaging techniques is the large amount of high dimensional visual data that is produced, often requiring GBs, or even TBs, of storage. READ MORE

20. Feature-Based Image Processing for Rendering, Compression, and Visual Search
Abstract : Visual communication, vivid, meaningful, and creative, permits a way to express information visually. The communication media, by images, graphs and videos, passes informative color and shape to human perception sensors. READ MORE
