    We propose applying MIDI technology to coding of physiologic sounds such as heart sounds used in medical diagnosis for constructing medical audio databases. Furthermore, we extend our encoding algorithm in order to apply it to other types of sounds such as bird sounds and human singing. We overview our proposed encoding algorithms, which consist of a real time coding method and a high precision co... View full abstract»

    Current video compression formats optimize for either compression or editing. For example, motion-JPEG (MJPEG) provides excellent random access and moderate overall compression, while MPEG optimizes for compression at the expense of random access. Converting from one format to another, a process called transcoding, is often desirable over the life of a video segment. The paper shows how to transco... View full abstract»

    Interactive movies have emerged as a new type of media that implements interaction capabilities into movies. In interactive movies, people enter cyberspace and enjoy the development of a story by interacting with characters in the story. We first explain the concept of interactive movies and briefly describe the prototype system we have developed. We then describe the construction of a second syst... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (208 KB)

    Various digital watermarking techniques have been proposed in recent years as the methods to protect the copyright of multimedia data. However, the rightful ownership problem has not been properly solved. Currently, there are two proposals to solve the ownership problem. Unfortunately, one proposal lacks a formal proof and the other can be easily defeated. We present watermarking methods which wil... View full abstract»

    This paper addresses the problem of rapid browsing of a large set of World Wide Web documents, such as the results of a search engine query or a bookmark list. Traditional presentations of such lists are in the form of text, and require careful attention and often laborious efforts in order to discover relevant documents. We propose a visual representation of documents, called a caricature, which ... View full abstract»

    We describe an infrastructure for multiple perspective interactive video (MPI-Video) systems. An MPI-Video system assimilates data from multiple disparate sensors, allowing a user to interact with them in a meaningful way. At the heart of an MPI-Video system is an environment model (EM) that both assimilates data from multiple sensors and acts as an information server to clients. A collection of s...

    The interoperability between heterogeneous distributed virtual environments is one of the main problem virtual reality will have to face in the very near future. This article presents the main concepts we propose in NOVA (Networked Open Virtual Environment). These concepts are presented as a set of paradigms based on the semantics of a virtual world and its virtual entities View full abstract»

  • Concealment of lost speech packets using adaptive packetization

    Publication Year: 1998, Page(s):140 - 149

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (144 KB)

    Long-term correlation within a speech signal is usually exploited to achieve higher compression ratios (e.g. RPE-LTP coders). We aim to use the long-term correlation to influence the packetization interval of a voice stream at the sender before sending it over a lossy packet-switched network. If a packet is lost, the receiver can conceal the loss of information by using adjacent signal segments of... View full abstract»

    Receiver playback buffers are required to smooth network delay variations. A playback buffer operates by introducing additional delay, acting as a holding area for packets whose scheduled playback time is in the future. Packets which arrive after their scheduled playback time are considered late and are discarded. The algorithms commonly used in the Internet are reactive, in that they measure imme...

    The paper studies the delay-jitter performance of MPEG2 video transmitted over a connection oriented internetwork consisting of various possible mixes of IP and ATM switches. It is shown that all-IP switching outperforms all-ATM switching when the network load is high, and vice versa at low network load. Mixed IP and ATM switching is shown to perform between these two cases. Several methods of map... View full abstract»

    We consider a content-based adaptive clustering algorithm (CBAC) to extract a fixed pre-determined number of representative frames to summarize a given digital video. In our algorithm, shot boundary detection is not needed. The inter-frame changes are compared globally for the extraction of representative frames. Small units of the video are dynamically clustered into two clusters based on the amo... View full abstract»

    We present an optimal scheduling algorithm called Periodic Write-Read-Compute (PWRC) scheduling for video processing. PWRC scheduling exploits continuity and periodicity of the video data. Therefore, it is suitable for any type of periodic data over which data independent application is to run.

    We present an experimental evaluation of three color-spatial retrieval techniques-the signature-based technique, the partition-based algorithm and the cluster-based method. The experimental study is performed on an image database consisting of 12000 images. With the proliferation of image retrieval mechanisms and the lack of extensive performance studies, the experimental results can serve as guid... View full abstract»

    We have developed a scalable reliable multicast architecture for delivering one-to-many telepresentations. In contrast to audio and video, which are often transmitted unreliably other media, such as slides, images and animations require reliability. Our approach transmits the data in two layers. One layer is for session-persistent data, with reliability achieved by FEC alone, using the Fcast proto... View full abstract»
