Motion Vector Predictor Selection and Adaptive Refinement Process for H.264/AVC Enhanced Predictive Zonal Search
Key technology area (KTA) proposed larger motion partition sizes than the macroblock of 16× 16 pixels to improve the performance of H.264/AVC in high resolution video coding. Even if coding efficiency is improved, it has high complexity due to increased motion partition blocks. Especially, the motion estimation part takes a large portion of complexity. Enhanced predictive zonal search (EPZS) is...
متن کاملMotion Estimation based on Artificial Fish-Swarm in H.264/AVC Coding
Motion estimation plays a key role in H.264/AVC video coding, but it is the most time-consuming task in the encoding process. In order to reduce the computational complexity of motion estimation in H.264/AVC video coding, this paper proposes a new search algorithm based on artificial fish-swarm algorithm (AFSA) which is a new efficient optimizing method. Firstly, some characteristics of AFSA ar...
