An Integrated Interframe Video Coding Scheme Based on Adaptive Directional Motion Search and Improved Mode Decision
Preview AbstractIn this paper, an improved interframe coding scheme consisting of both the adaptive directional motion search and improved mode selection is proposed to reduce the computational complexity of video coding. The motion direction is divided into four regions, and different multi-hexagon templates are designed for each region to enhance directional search, which can improve the search accuracy. Subsequently, the improved mode decision that integrates the detection of all zero blocks is proposed for further computation reduction. Experimental results demonstrate that the proposed scheme can reduce encoding time by an average of 60% while maintaining almost the same coding efficiency as existing fast interframe coding schemes.
