In this paper, a no reference bit stream model for quality assessment of SD and HD H.264/AVC video sequences based on packet loss visibility is proposed. The method considers the ...
Approximately 2 degrees in our 140 degree vision span has sharp vision. Many researchers have been fascinated by the idea of eyetracking integrated perceptual compression of an im...
We study the application of Unequal Loss Protection (ULP) algorithms to motion-compensated video over lossy packet networks. In particular, we focus on streaming video applications...

We propose the use of attentional cascades based on the DCT and motion information contained in an MPEG coded stream. An attentional cascade is a sequence of very efficient class...
The Digital Systems and Media Computing Laboratory (DSMC Lab) was established in the end of 2002 and is located in Patras, Greece. DSMC operates under the School of Sciences and Te...

MPEG, the Mowing Picture Experts Group, is a popular compression standard used in many multimedia applications. In video distribution systems, a CBR communications channel is ofte...
Scalable video is an attractive option for adapting the bandwidth consumption of streaming video to the available bandwidth. Fine-grained scalability can adapt most closely to the...

This paper describes a fully automatic content-based approach for browsing and retrieval of MPEG-2 compressed video. The first step of the approach is the detection of shot bound...
