— Research on multimedia adaptation usually assumes undifferentiated, best-effort service from the network, and relies on signaling mechanisms such as packet loss rates for feedb...
Most of the existing work on modeling variable bit rate (VBR) video sources does not either explicitly take into account groupof-pictures (GOP) or assumes a fixed GOP structure. R...
When both TCP and UDP sessions co-exist in the Internet, the performance of TCP sessions easily deteriorate because of congestion incurred by UDP sessions of real-time multimedia ...
Relevance feedback [1] has been a powerful tool for interactive Content-Based Image Retrieval (CBIR). During the retrieval process, the user selects the most relevant images and p...
One of the difficulties of Content-Based Image Retrieval (CBIR) is the gap between high-level concepts and low-level image features, e.g., color and texture. Relevance feedback wa...
In this paper, we propose a language called QOS-SMIL where some QoS guarantee statements are added to a subclass of SMIL, and give its implementation technique. In QOS-SMIL, in ad...
In order to understand similarity between images, recent research has focused on adaptable searches [9] and fuzzy queries [4]. However, one of the best means for determining simil...

This paper addresses the problem of bit-rate conversion of MPEG compressed video. We present selective requantization, a method for reducing the requantization errors in transcodi...
A Joint source-channel coding (JSCC) scheme for SPIHT coded image transmission over OFDM systems with spatial diversity is proposed where no feedback channel is available. By usin...
