Compressed video may possess a number of artifacts, both spatial and temporal. Spatial compression artifacts arise as a result of quantization of the transform-domain coefficients, and are often manifested as blocking and ringing artifacts. Temporal limitations in compressed video occur when the encoder, in an effort to reduce bandwidth, drops frames. Omitting frames decreases the reconstructed...

An algorithm is proposed for the detection of abrupt scene change and special editing effects such as dissolve in a compressed MPEG/MPEG-2 bitstream with minimal decoding of the bitstream. Scene changes are easily detected with DCT DC coefficients and motion vectors. By performing minimal decoding on the compressed bitstream, the processing speed for searching a video database of compressed ima...

In this paper, we proposed a robust moving video object segmentation algorithm using features in the MPEG compressed domain. We first cluster the motion vectors and produce a motion mask. Then, a difference mask at 8 x 8 block size is extracted from the DC image by background subtraction method. Finally, the motion mask and the difference mask are combined conditionally to generate the final ob...

This work considers object repetition, which means the occurrence of same object with similar motion is repeated in two or more frames. A single video is divided into several frames. All the objects are extracted from the stationary background and their features like motion and shape are preserved. After extraction, a two step compression is employed in which the algorithm checks for the contin...

The recent successes of over-the-top (OTT) video services have intensified the competition between the traditional broadcasting video and OTT video. Such competition has pushed the traditional video service providers to accelerate the transition of their video services from the broadcasting video to the carrier-grade IP video streaming. However, there are significant challenges in providing lar...

The paper proposes a novel approach to the classification of compressed videos containing dynamic textures. The term dynamic texture is usually used with reference to image sequences of various natural processes that exhibit stochastic dynamics (e.g., water, fire and windblown vegetation). Description and recognition of dynamic textures have attracted growing attention. Although one of the most...

Transporting video over asynchronous transfer mode (ATM) networks has been an active area of research. The Variable Bit rate (VBR) service in ATM networks is primarily designed and used for real time application like compressed voice and video. Due to compressed video is inherently bursty, the bandwidth could not be efficiently utilized. The explicit rate (ER) flow control designed for Availabl...

Moving object completion is a process of completing moving object’s missing information based on local structures. Over the past few years, a number of computable algorithms of video completion have been developed, however most of these algorithms are based on the pixel domain. Little theoretical and computational work in video completion is based on the compressed domain. In this paper, a movi...
