    New activities in the video coding community are focused on the delivery of technologies that will enable economic handling of future visual formats at very high quality. The key characteristic of these new visual systems is the highly efficient compression of such content. In that context this paper presents a novel approach for intra-prediction in video coding based on the combination of spatial... View full abstract»

    This paper presents a design of new video coding scheme targeting substantial compression performance with reasonable complexity for next-generation high-resolution video sources. While it takes a conventional block-based MC+DCT hybrid coding approach that is suitable for hardware implementation of a high-resolution video codec, the proposed scheme achieved significant improvement of coding effici...

    Over the past few decades, many studies on image and video compression have found various approaches to the exploitation of spatial and temporal local correlations. However, we believe it is imperative to find more efficient methods to progress the development of image and video compression. In this paper, we first study spatial non-local correlation, deducing that there exist strong correlations ... View full abstract»

    Object-based video coding has been of interest for many years. Recent work by the authors has shown that a video coding system using background Sprites with automatic segmentation and background subtraction can indeed perform better than the H.264/AVC coder. In this paper, we extend this work by developing a rate-distortion optimization approach for an object-based coder. A key issue addressed by ... View full abstract»

    This paper presents a foveated coding method using audio-visual focus of attention and its evaluation through extensive subjective experiments on both standard-definition and high-definition sequences. Regarding a sound-emitting region as the location drawing the human attention, the method applies varying quality levels in an image frame according to the distance of a pixel to the identified soun...

    3DTV technology has brought out new challenges such as the question of synthesized views evaluation. Synthesized views are generated through a depth image-based rendering (DIBR) process. This process induces new types of artifacts whose impact on visual quality has to be identified considering various contexts of use. While visual quality assessment has been the subject of many studies in the last... View full abstract»

    This paper presents an efficient depth map coding method based on a newly defined rendering view distortion function. As compared to the conventional depth map coding in which distortion is measured by only investigating the coding error in depth map, the proposed scheme focuses on virtually synthesized view quality by involving co-located color information. In detail, the proposed distortion func... View full abstract»

    In this paper, we investigate the use of linear, parametric models of static and dynamic texture in the context of conventional transform coding of images and video. We propose a hybrid approach incorporating both conventional transform coding and texture-specific methods for improvement of coding efficiency. Regarding static (i.e., purely spatial) texture, we show that Gaussian Markov random fiel... View full abstract»

  • Segmentation-Based Video Compression Using Texture and Motion Models

    In recent years, there has been a growing interest in developing novel techniques for increasing the coding efficiency of video compression methods. One approach is to use texture and motion models of the content in a scene. Based on these models parts of the video frame are not coded or “skipped” by a classical motion compensated coder. The models are then used at the decoder to rec... View full abstract»

    This paper presents a novel means of video compression based on texture warping and synthesis. Instead of encoding whole images or prediction residuals after translational motion estimation, our algorithm employs a perspective motion model to warp static textures and utilizes texture synthesis to create dynamic textures. Texture regions are segmented using features derived from the complex wavelet... View full abstract»
