基于小波变换的改进AMMC去隔行算法

摘要

To raise the resolution of the image, this paper presents an improved Adaptive Morphologic Motion Compensation(AMMC) de-interlacing algorithm. It is based on reversibility of wavelet transform to employ the wavelet transform for the post-processing stage. It preserves the edge, and reduces the interpolation error of the motion compensation by using the spatial-temporal correlation and weighting the wavelet coefficients. Experimental results show that the algorithm can reduce the ambiguity of the image edge, and accomplish the better image quality.%为提高图像的分辨率,提出一种改进的AMMC去隔行算法.基于小波变换的可逆性,利用相邻像素间的空间和时间相关性,通过自适应加权小波系数,保持图像边界平滑以及减小运动补偿插值后的误差.实验结果表明,改进算法能降低图像边缘的模糊度,具有较高的画面质量.
