In this work, we address the complexity of the most time consuming module of High Efficiency Video Coding (HEVC) Intra-encoding, i.e. the Intra prediction generation. We reduce the computational complexity by estimating the candidates list (most probable Intra prediction modes), using content- and priority-driven gradient detection and hierarchically gathering the results of previous computations...
The next-generation High Efficiency Video Coding (HEVC) standard aims at providing double compression compared to the state-of-the-art H.264/AVC standard. However, this improved compression efficiency accompanies high computational complexity, which is primarily due to the recursive nature of the Coding Tree Unit structure and complex Rate-Distortion (RD) Optimization of Prediction Units (PU). In...
A novel complexity reduction scheme for Multiview Video Coding (MVC) is presented that adaptively eliminates the less-probable Motion or Disparity Estimation (ME, DE) search directions and less-probable block coding modes. Based on their texture difference w.r.t. the current Macroblock, matching neighbors in the 3D-neighborhood (spatial, temporal, view domains) are identified. Our scheme employs a...
In this paper, we propose a novel scheme for dynamically reducing the computational complexity of MVC. Our scheme exploits the coding mode correlation available in the 3D-neighborhood (i.e., spatial, temporal, and view) along with the rate-distortion properties of the neighboring Macroblocks. Our scheme incorporates a multi-level mode decision process based on a mode-ranking mechanism that categorizes...
We propose a novel power-aware scheme for complexity-scalable multiview video coding on mobile devices. Our scheme exploits the asymmetric view quality which is based on the binocular suppression theory. Our scheme employs different quality-complexity classes (QCCs) and adapts at run time depending upon the current battery state. It thereby enables a run-time tradeoff between complexity and video...
