    Partitioning a video sequence into shots is the first step toward video-content analysis and content-based video browsing and retrieval. A video shot is defined as a series of interrelated consecutive frames taken contiguously by a single camera and representing a continuous action in time and space. As such, shots are considered to be the primitives for higher level content analysis, indexing, an... View full abstract»

    This paper presents a twin-class transmission system for narrowband radio access channels suitable for handheld video phone and multimedia portable PC applications. The transmission system is comprised of a hierarchical 16-QAM modulation technique and a channel-coding scheme. The formation of dual-priority transmission is due to differing error resiliencies of the bits that make up a given symbol ... View full abstract»

    We propose an image-coding algorithm which combines the discrete cosine transform (DCT) and the singular value decomposition (SVD). The DCT is used to transform those blocks in the source image that exhibit a high correlation, while blocks with greater high-frequency content are transformed using the SVD. A simple criterion is used to decide which transform should be used on each block. Simulation... View full abstract»

    The new video-coding standard MPEG-4 enables content-based functionality, as well as high coding efficiency, by taking into account shape information of moving objects. A novel algorithm for segmentation of moving objects in video sequences and extraction of video object planes (VOPs) is proposed . For the case of multiple video objects in a scene, the extraction of a specific single video object ... View full abstract»

  • Region-of-interest coding based on set partitioning in hierarchical trees

    In many image-coding applications such as Web browsing, image databases, and telemedicine, it is useful to reconstruct only a region of interest (ROI) before the rest of the image is reconstructed. In this paper, an ROI coding functionality is incorporated with the set partitioning in hierarchical trees (SPIHT) algorithm for wavelet-based image coding. By placing a higher emphasis on the transform... View full abstract»

    Research has shown that the sight of a speaker's face can dramatically improve the intelligibility of speech. The addition of a video stream to telecommunications systems is, therefore, a highly desirable goal. Extending the content-based coding paradigm of MPEG-4, we present a novel method of reducing the amount of data required to represent video images of human speakers. This method is based ar...
