Compressed video transmission over UDP/IP-based networks leads some challenging studies. One of them refers to the problem of minimizing the burstiness of video compressed traffic as it leads to poor network bandwidth utilization. Video smoothing has been proposed as one solution to this problem. This paper presents a smoothing algorithm to reduce such burstiness. The algorithm can bring good r...

Fast and eecient storage, browing, indexing, and retrieval of video is necessary for the development of various multimedia database applications. Given that video is typically stored eeciently in a compressed format, if we can analyze the compressed representation directly, we can avoid the costly overhead of decompressing and operating at the pixel level. Compressed domain parsing of video has...

Development of various multimedia applications hinges on the availability of fast and eecient storage, browsing , indexing, and retrieval techniques. Given that video is typically stored eeciently in a compressed format, if we can analyze the compressed representation directly, we can avoid the costly overhead of decompressing and operating at the pixel level.

In this paper, we discuss methods for coding MPEG-4 video to enable better computer vision on the compressed video. This problem is important since the amount of video content being generated from a variety of sources is increasing very rapidly, almost all this video is in compressed form, and computer vision applications such as video analysis, mining and querying running on these videos are b...

In this paper we propose a new method for video resolution enhancement from compressed video data. Novelty of the approach is that resolution enhancement is done by interpolating the motion vectors. Proposed method works very well for different compression methodologies. We first discuss zooming, when the video is compressed using the Discrete Cosine Transform Domain (DCT). Next we use the Disc...

We tested how to improve the quality of the reconstructed video, several deblocking algorithms have been used. In this paper, we will introduce these deblocking algorithms and classify them into several categories. On the other hand, the conventional PSNR is widely adopted for estimating the quality of the compressed video. However, PSNR sometimes does not reveal the quality perceived by human ...

Recently, soft video multicasting has gained a lot of attention, especially in broadcast and mobile scenarios where the bit rate supported by channel may differ across receivers, vary quickly over time. Unlike conventional designs that force source to use single according receiver with worst quality, delivery schemes transmit such quality at each is commensurate its specific instantaneous quali...
