Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...

Video compression technology for Ultra-High Definition (UHD) and 8K UHD video has been established is being widely adopted by major broadcasting companies content providers, allowing them to produce high-quality videos that meet the demands of today’s consumers. However, high-resolution not an easy problem be resolved in near future due limited resources network bandwidth data storage. An alter...

Closed-loop video rendering implies generating video streams in compressed form given as input video streams that are in compressed form such as JPEG or MPEG bit streams. Closed-loop video rendering has signi cant advantages over open-loop schemes including reduced storage requirements which in turn reduces memorydisk swapping time that constitutes a large portion of the time spent in the deskt...

compressed domain processing, transcoding, video editing, MPEG, splicing, reverse play, frame rate conversion, interlace to progressive, motion vector resampling Video compression algorithms are being used to compress digital video for a wide variety of applications, including video delivery over the Internet, advanced television broadcasting, video streaming, video conferencing, and video stor...

Indexing and editing digital video directly in the compressed domain offer many advantages in terms of storage efficiency and processing speed. We have designed automatic tools in the compressed domain for extracting key visual features such as scene cut, dissolve, camera operations (zoom, pan), and moving object detection and tracking. In addition, we have developed algorithms to solve the dec...

Multi-point network video services require compositing several video sources into a single displayed video stream. Compositing video directly in the compressed domain can save computations by processing less data and avoiding the conversion process back and forth between the compressed and uncompressed data formats. Earlier work has demonstrated the computational speedup of compositing DCT-comp...
