基于小波域中值滤波和运动估计的去隔行算法

本文提出了一种新的自适应去隔行算法,该方法首先将小波分解引入到去隔行算法的预处理阶段,然后利用运动估计以及混合中值滤波的特点,充分考虑相邻像素间的方向空间相关性,有效保持图像中的边界部分,并减小了运动补偿插值后的误差,尤其是对纹理信息丰富的地方得到了很好的插值效果.实验结果表明,无论是从客观上的信噪比还是主观测评来分析,图像的效果比传统的算法有了提高,能更好的满足人类对画面质量的要求.

An De-interlacing Technique with Motion Estimation and Hybrid Median Filter in Wavelet Domains

A novel de-interlacing algorithm with motion estimation and hybrid median filter is introduced.The novel method employs the wavelet analysis firstly to distinguish the high and low frequency handled using different median filter,and then gets the value of the ME and MF.It utilizes the correlative information of space and time of the video signal.Experimental results show that the proposed method gives better quantitative and a better visual performance than the traditional median filter method.
