16. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement
Sammanfattning : 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. LÄS MER
17. Interpolation Techniques with Applications in Video Coding
Sammanfattning : 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. LÄS MER
18. Development, analysis and implementation of pre-processing video filters
Sammanfattning : The usage of video systems in households and industry has increased rapidly over the past few years. The benefits of visual processing, control and inspection have offered great opportunities for real-time video processing systems (RTVPS) for the general public as well as for heavy industries.

19. Sparse representation of visual data for compression and compressed sensing
Sammanfattning : 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. LÄS MER
20. Feature-Based Image Processing for Rendering, Compression, and Visual Search
Sammanfattning : 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. LÄS MER
