    Research by content in image databases should benefit from the database approach as much as from the image processing and analysis field. Previously, we emphasized the use of a query language in an object-oriented database, namely OQL (Object Query Language) and O2 . This offers greater expressive power, flexibility, direct mixing with structured data, and the possibility to store the q... View full abstract»

    Colour is an important attribute for image matching and retrieval, and relevance feedback (RF) has been found to improve the retrieval effectiveness in information retrieval systems significantly. We propose a new approach for colour-based RF for image retrieval. The approach makes use of the Multi-Interval Discretization Algorithm to discretize the range of colour histogram values into discrete c... View full abstract»

    Most applications that access large data objects do so through file systems, but file systems provide an incomplete solution, as they maintain insufficient metadata and do not provide general purpose query engine. Storing large objects in a database addresses these problems, but, for applications that need to update object data, databases are inefficient as they do not provide direct access to dat...

    Most multimedia servers reported in the literature are designed to serve multiple and independent video/audio streams. We think that, in the future, multimedia servers will also serve complete presentations. A multimedia presentation contains explicitly specified synchronization information describing when each multimedia data needs to be delivered in the playout of the presentation. Multimedia pr...

    We present a content-based query system in an image database. Queries are based on color, shape content and textual description of images. We show that without efficient synergy between image analysis techniques, more particularly mathematics, and database technology, it is very difficult to find effective, feasible and efficient solutions to the problem of retrieval in visual information systems....

    Contrary to current approaches which generally treat the video data as a random collection of static images, content-based video retrieval requires methods for video sequence-to-sequence matching incorporating the temporal order inherent in video data. We formulate the problem of video sequence-to-sequence matching as a pattern matching problem. New string edit operations required for the special ... View full abstract»

    We describe a new approach to fission of multimedia information based on the concept of active documents advertising on the Internet, whereby a document dynamically builds metadata, joins a group of documents of the same interest and advertises the collected metadata to the members of the group. This abstraction of metadata is called an adlet, which is the core of our approach. This approach suppo... View full abstract»

    Visual database systems require efficient and effective mechanisms for content-based retrieval. Content of an image can be expressed in terms of different features such as shape, color, texture, or text annotations. Retrieval based on each of these individual features can result in a different set of images. Thus, there is a need to merge the results obtained from these individual heterogeneous fe...

    Presents a rich model for interactive multimedia presentations and an implemented authoring system based on the model. The model covers the issues of interaction in terms of external and internal events and also the spatiotemporal composition of media objects in the context of the presentation. The authoring is carried out in three consecutive phases related to: (i) selection and transformations o... View full abstract»

    Multimedia database systems (MMDBSs) have to be capable of efficiently handing time-dependent and time-independent data, and of supporting quality of service (QoS). To support continuous playout of time-dependent data, reservations of the resource-limited disk I/O bandwidth and network bandwidth have to be combined with appropriate buffer management. Based on the special requirements of the DEDICA... View full abstract»

    Conventional file systems are unable to guarantee that clients can access continuous media in a way that permits delivery deadlines to be met under normal buffering conditions. This is due to the fact that magnetic disks and optical disks have large seek and rotational latencies that can cause a continuous media client to starve if the continuous medium is not buffered and coordinated with other s...

    Multimedia database management systems require high capacity and performance from secondary storage in terms of fast and uninterrupted retrieval of data objects. In addition, responding to a user query in a timely manner by searching a huge database to retrieve relevant data objects is an important operation in a multimedia system. A variety of parallel optical storage techniques combine massive c... View full abstract»

    This paper discusses scheduling of random I/O requests for multimedia data stored on magnetic tape using serpentine data layout. Results from simulations and real experiments show that substantial improvements of retrieval performance can be achieved by proper I/O scheduling.

    The phenomenal increase in the amounts of audio (and multimedia) data being generated, processed, and used in several computer applications have necessitated the development of audio (and multimedia) database systems with newer features such as content-based queries and similarity searches to manage and use such data. Example applications of audio databases are in digital libraries, entertainment ... View full abstract»

    Recent research has shown that near-optimal performance can be achieved by adaptive block replacement policies that use user-level hints regarding the block reference pattern. However, obtaining user-level hints requires considerable effort from users, making it difficult to apply adaptive replacement policies to diverse kinds of applications. We propose a new adaptive block management scheme that... View full abstract»

    An algorithm for detecting scene changes in compressed video streams is proposed. The proposed algorithm directly exploits the motion compensation information and the prediction error signal in the MPEG1-coded video stream. By performing minimal decoding of the compressed video stream, the proposed algorithm results in significant savings in terms of execution time and memory requirement. Experime...

    A method is introduced that detects human faces in color images by first separating skin regions from non-skin regions and then locating faces within the skin regions. A chroma chart is prepared via a training process that shows likelihoods of different colors representing the skin. Using the chroma chart, a color image is transformed into a gray-scale image, with the gray value at a pixel showing... View full abstract»

    Presents a conceptual data model for multimedia database applications based on the ExIFO2 (Extraction of Information from Fuzzy Object-Oriented data) model. This data model is chosen as the conceptual model since it handles both complex objects along with their uncertain and imprecise properties.

    Recently, much attention has been paid to interactive temporal models which let authors define possible interactions with users and represent the dynamic organization of hypermedia documents. The possibility of user interaction makes it very hard for authors to predict the course of presentation and to author a document without an authoring tool. The authoring tool must then be designed with a ric... View full abstract»

    Video retrieval is one of the important design issues of multimedia database management systems. The distinguished features of video retrieval lie in the similarity measures and content-based retrieval. Most research on content-based video retrieval represents the content of video as a set of frames leaving out the temporal ordering of frames in the shot. In this paper, the similarity measures of ... View full abstract»

    Still image watermarking has gained considerable interest. Digital video, however, has received comparatively less attention. In this work we present a formal framework for digital video watermarking. The video signal is modeled as sequence of bitplanes arranged along the time axis. Watermarking of this sequence is a two layer operation. A controlling m-sequence first establishes a pseudorandom or... View full abstract»
