چکیده
By 2022, we expect video traffic to reach 82% of the total internet traffic. Undoubtedly, abundance video-driven applications will likely lead percentage a further increase in near future, enabled by associate advances devices' capabilities. In response this ever-growing demand, Alliance for Open Media (AOM) and Joint Video Experts Team (JVET) have demonstrated strong renewed interest developing new codecs. fast-changing codecs' landscape, there is thus, genuine need develop adaptive methods that can be universally applied different study, formulate encoding as multi-objective optimization process where quality (as function VMAF PSNR), bitrate demands, rate (in encoded frames per second) are jointly optimized, going beyond standard approaches focus on control targeting specific bandwidths. More specifically, create dense space (offline) then employ regression generate forward prediction models each one afore-described objectives, using only Pareto-optimal points. We demonstrate our approach leverages generated qualify real-time adaptation codecs (e.g., SVT-AV1 x265) variety datasets resolutions. To motivate establish promise future fast VVC encoders, also perform comparative performance evaluation both subjective objective metrics report savings among all possible pairs between VVC, SVT-AV1, x265, VP9

An Efficient Adaptive Boundary Matching Algorithm for Video Error Concealment
Sending compressed video data in error-prone environments (like the Internet and wireless networks) might cause data degradation. Error concealment techniques try to conceal the received data in the decoder side. In this paper, an adaptive boundary matching algorithm is presented for recovering the damaged motion vectors (MVs). This algorithm uses an outer boundary matching or directional tempo...
متن کاملScene adaptive video encoding for MPEG and H263+ video
Digital video requires much higher data rates and transmission bandwidths. However the statistical analysis of video signals indicates that there is a strong correlation both between successive picture frames and within the picture elements themselves. Theoretically decorrelation of these signals can lead to bandwidth compression without significantly affecting image resolution. Moreover. the i...
متن کاملAdapting Standard Video Codecs for Depth Streaming
Cameras that can acquire a continuous stream of depth images are now commonly available, for instance the Microsoft Kinect. It may seem that one should be able to stream these depth videos using standard video codecs, such as VP8 or H.264. However, the quality degrades considerably as the compression algorithms are geared towards standard three-channel (8-bit) colour video, whereas depth videos...
متن کاملOptimization of Low−delay Wavelet Video Codecs
Abstract : The paper deals with lifting implementations of the motion−compensated temporal filter banks in the (t+2D) wavelet codecs. The paper is focused on the problem of optimum setup of the analysis and synthesis filters with the maximum coding efficiency possible for a given delay constrain. Systematic exhaustive experiments have been performed in order to find optimum setup as well as cod...
متن کاملSIC and Wavelet Software Video Codecs
In order to achieve low bit rate transmission of video data, compression techniques are needed. Segmented image coding (SIC) and wavelet are two relatively new but powerful techniques used for compression of still images and/or video. The low complexity of these compression techniques allows software implementation on general purpose processors. A SIC and a wavelet compression algorithm, propri...
