摘要
为了进一步降低计算复杂度,提高视频图像的质量,通过对帧间预测模式的运动补偿分析及图像的频谱分析,提出了一种基于帧间预测模式的插值滤波器算法。该算法对每个不同的分块编码模式使用不同阶次的插值滤波器,为每一个分块编码模式选择最优的插值滤波器。实验结果表明,该算法不仅能有效地降低计算复杂度,还能提高信噪比,使图像的质量得到进一步的改善。
In order to further reduce the computational complexity and improve the quality of video images,the motion compensation of the inter-frame prediction model and the image spectrum are analyzed.An interpolation filter algorithm based on the inter-frame pre-diction mode is presented.For each different sub-block coding mode,a different class of interpolation filter is used and the optimal in-terpolation filter is selected.The experimental results show that the algorithm can not only reduce the encoding complexity effectively,but also improve the signal to noise ratio and the quality of the image.
