A Novel Motion Vector Refinement Algorithm for Spatial Resolution Reduction Transcoding

چکیده
For the low bit-rate video communications, video contents have to be transcoded according to network bandwidth and the performance of clients. The heterogeneous low bit-rate transcoding, however, suffers from quality degradation caused by the drift error. In this paper, we propose a novel motion estimation refinement algorithm to compensate drift errors. Simulation results show that the proposed algorithm not only preserves original image quality, but also reduces the computational complexity of spatial resolution reduction transcoding.

Heterogeneous Video Transcoding to Lower Spatio-Temporal Resolutions and Different Encoding Formats
In this work, transcoding of pre-encoded MPEG-1, 2 video into lower bit rates is realized through altering the coding algorithm into H.261/H.263 standards with lower spatio-temporal resolutions. For this heterogeneous transcoding, we extract and compose a set of candidate motion vectors, from the incoming bit stream, to comply with the encoding format of the output bit stream. For the spatial r...

متن کاملVideo Conferencing Oriented Low-Complexity Coarse-Level Mode-Mapping Based H.264/AVC to H.264/SVC Spatial Transcoding
As an extension of H.264/AVC, Scalable Video Coding (SVC) provides flexible adaptation to heterogeneous networks and end-users, which provides great scalability for applications such as video conferencing. However, due to the existence of legacy H.264/AVC-based systems, transcoding between AVC and SVC becomes necessary. Currently there are few works done on AVC-to-SVC spatial transcoding, and r...
