This paper presents a mechanism of using rectangular prediction blocks for Intra prediction in the emerging High Efficiency Video Coding (HEVC) standard. In the previous and current video coding standards, Intra predictions have been processed on square blocks, e.g. 16×16, 8×8 and 4×4 pixel blocks H.264/MPEG4 AVC, and 2N×2N or N×N square prediction units (PU) in the current HEVC. In this paper, it...
New High Efficiency Video Coding (HEVC) standard is designed to provide substantial coding efficiency improvement compared to H.264/AVC. Latest subjective testing shows 50% improvement has been achieved. Many new technologies contribute to the overall improvement. Intra prediction with 35 modes is one of the key improvements. Associated with that, there is a new intra mode coding method to efficiently...
In the ISO/IEC 14496-10 |ITU-T H.264 advanced video coding (AVC) standard, the prediction block sizes can be 16×16, 8×8 and 4×4 for Intra prediction; 16×16, 16×8, 8×16, 8×8, 8×4, 4×8 and 4×4 for Inter prediction. In the first HEVC test model (HM1.0), each 2N×2N Intra CU may consist of either one 2N×2N prediction unit (PU) or four N×N prediction units; while each 2N×2N Inter CU may consist of one 2N×2N...
In this paper the trajectory tracking control of the arm rehabilitation robot for stroke patients is investigated by an interactive robust control approach. The functions of patients' voluntary joint torques are designed depending on the motion ability of their arms, and the dynamic model of the human-robot system is presented. Based on the dynamic model, an interactive controller is designed to provide...
