AN UP-SAMPLING METHOD AND SYSTEM FOR SPATIAL LAYERED CODING VIDEO PICTURES

摘要

A video picture compressing technology, particularly an up-sampling method and system for spatial layered coding video pictures, cause that in the process of up-sampling, the computational complexity is reduced, while the coding performance is constant. The invention uses the principle that the human eyes' sensitivity to the chrominance component is significantly less than it to the luminance component, in the up-sampling process of I_BL inter-layer prediction or residual error picture inter-layer prediction, compared to the luminance component, it uses the more simpler filter for the chrominance component, thereby reduces the computational complexity, while maintains the coding performance.
