An adaptive sharpening filter using quantization step size and pixel variance in H.264/AVC
Consumer Electronics（2011）
摘要
In this paper, we present an adaptive sharpening filter for a pre-processing to improve the subjective quality and the performance of H.264/AVC compression. We use quantization step size and pixel variance to select sharpening filter strength. The simulation results show that the proposed pre-processing filtering process improves the subjective quality and reduces bit rate about 0.85%(CIF) and 1.46%(1080p).
