Abstract:

On the basis of H.264/AVC video coding standard, an improved subpixel search algorithm was presented via the analysis of the current UMHexagonS algorithm processes and problems, optimization of the entire pixel search algorithm UMHexagonS with the improved UMHexagonS algorithm process given. Experimental results show the improved algorithm, on the premise of ensuring the quality of the images, significantly reduces the encoding time and improves the coding efficiency.
