Adaptive Hierarchical Clustering Algorithm (AHCA) maps a flat topology to a hierarchical tree though output trees are incontrollable and are not suitable for multimedia. PruneRel...
XML is becoming increasingly popular as the ubiquitous standard for metadata; consequently, it is being incorporated into many multimedia applications, such as those based on MPEG...
This paper presents a geometric error concealment scheme for DCT-based image/video data based on the Bezier polynomials (BP). The proposed scheme makes use of the average edge dir...
A robust learning-based TV commercial detection approach is proposed in this paper. Firstly a set of basic features that facilitate distinguishing commercials from general program...
This paper presents the optimization techniques and results of implementing the H.264/AVC baseline profile decoder in software on the Sandblaster digital signal processor. It has ...
This paper presents experiments that evaluate the effect of different video segmentation methods on text-based video retrieval. Segmentations relying on modalities like speech, vi...
Peer-to-Peer (P2P) multimedia application is expected to be one of the most important services supported by the next generation networks. However, how to balance server load in re...
In this paper, a method for content-based retrieval of JPEG images is presented, utilizing features directly from the discrete cosine transform (DCT) domain. Image indexing is ach...
