摘要
针对去方块效应滤波的边界强度判断和滤波过程计算量大的情况,本文提出了一种新的去方块效应滤波算法,分别对边界强度判断和滤波过程的算法进行优化。综合两部分的优化算法,通过实验结果得知,降低的算法复杂度平均值达到了9.82%、峰值信噪比(PSNR)平均值也增加了0.119 dB。该算法既降低了算法的复杂度又改善了压缩后视频的质量。
Aiming to large amount of calculation of the boundary strength (BS) judgment and faltering process of the de-blocking fiher,an efficient de-blecking filter algorithm is introduced, The boundary strength judgment and the filtering process algorithm are optimize separately. Experimental results show that the reduce algorithm complexity average reaches 9.82% and the average peak signal-to-noise ratio (PSNR) increases O. 119dB. With the efficient algorithms not only the complexity of the algorithm is reduce,but also the quality of compressed video is raised.
