    Multimedia applications usually involve a large number of multimedia objects (texts, images, sounds, etc.). Spatial and temporal relationships among these objects should be efficiently supported and retrieved within a multimedia authoring tool. In this paper, we present several spatial, temporal and spatio-temporal relationships of interest, and propose efficient indexing schemes, based on multidi... View full abstract»

    We present a novel technique for embedding digital "watermarks" into digital audio signals. Watermarking is a technique used to label digital media by hiding copyright or other information into the underlying data. The watermark must be imperceptible or undetectable by the user and should be robust to attacks and other types of distortion. In our method, the watermark is generated by filtering a P...

    Automatic image recognition is usually difficult. However, drama is composed of not only image but also sound and script. Therefore, higher level recognition of drama which cannot be achieved by the image analysis will be realized by integrating image analysis, sound analysis and document analysis. In this paper, focusing on the semantic descriptions in the script, content-based drama editing base... View full abstract»

  • On optimal batching policies for video-on-demand storage servers

    Publication Year: 1996, Page(s):253 - 258
    Cited by:  Papers (101)  |  Patents (37)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (524 KB)

    In a video-on-demand environment, batching of video requests is often used to reduce I/O demand and improve throughput. Since viewers may defect if they experience long waits, a good video scheduling policy needs to consider not only the batch size but also the viewer defection probabilities and wait times. Two conventional scheduling policies for batching are first-come-first-served (FCFS) and ma... View full abstract»

    Content based browsing and navigation in digital video collections have been centered on sequential and linear presentation of images. To facilitate such applications, nonlinear and non sequential access into video documents is essential, especially with long programs. For many programs, this can be achieved by identifying underlying story structures which are reflected both by visual content and ... View full abstract»

  • Shape discrimination using integral features

    Publication Year: 1996, Page(s):223 - 228
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (528 KB)

    “Integral features” are calculated by summing the local features over all the pixels, where the local features are determined by the state of the neighborhood of each pixel. The states are defined by using a two-dimensional series of mask functions on the polar coordinate system with the logarithmic scale of r-direction. This definition enables the efficient extraction of features from... View full abstract»

    Multimedia applications are characterized by QoS (quality of service) requirements, which depend an the quality of video and audio transmitted to the client, and the respect of time constraints associated with video and audio data. Much work has been done in order to provide system support that meets these requirements. However, existing proposals do not include the consequences of failure occurre... View full abstract»

    We propose a new index structure called the HG-tree, to support content-based retrieval in multimedia databases. Our goals are twofold: increasing the storage utilization and decreasing the directory coverage of the index tree. The first goal is achieved by absorbing splitting if possible, and when splitting is necessary, converting two nodes to three. This is done by proposing a good ordering on ... View full abstract»

    Multimedia feedback remote control applications use a control loop between devices such as robot manipulators and cameras and a human user. An application-to-application quality of service is required. Network and end-point resources must be controlled and integrated in a robust admission and scheduling process.

  • A greedy-but-safe dynamic scheduling strategy for an interactive video-on-demand server

    Publication Year: 1996, Page(s):136 - 143

    We study a dynamic approach to the problem of scheduling real time requests in a video on demand server. Most of the previous VOD scheduling approaches use limited run time information, and thus cannot exploit the potential capacity fully. Our approach improves throughput by making use of run time information to relax admission control, and to reduce admission to start delay by providing earliest ... View full abstract»
