A Direction-Based Unsymmetrical-Cross Multi-Hexagon-Grid Search Algorithm for H.264/AVC Motion Estimation


The Unsymmetrical-cross Multi-hexagon-grid Search (UMHexagonS) is one of the best fast Motion Estimation (ME) algorithm in H.264/AVC (Advanced Video Coding) reference software. It achieves an excellent coding performance by using multiple initial search point predictors and hybrid block matching search pattern. However, the hybrid search pattern makes the… (More)
