摘要

我们引入了一种新的多级非线性滤波器，用于同时进行边缘检测和噪声抑制，我们称之为嵌套中值滤波器-中值平均滤波器(NMF/MAF)对[13]。基于NMF/MAF对，我们提出了一种交错到渐进(I/P)转换来估计HD-MAC系统的运动向量。HD-MAC应用的测试结果证实了所提出的上转换方案在保持锐利边缘、抑制边缘移动和抑制脉冲噪声方面具有鲁棒性。此外，采用所提出的I/F转换方案的运动补偿内插HDMAC图像序列的PSNR(峰值信噪比)比隔行处理的图像序列提高了4-6 dB。

Interlaced To Progressive Conversion Based On New Median Filter Pair

We introduce a new multi-level nonlinear filter for simultaneous edge detection and noise suppnxsion, which we call a nested median filterlmedian averaging filfer(NMF/MAF) pair[ 13. Based on NMF/MAF pair, we propose an interlaced to progressive(I/P) conversion to estimate a moving vector for HD-MAC system. Test results for HD-MAC application confirm that the proposed Up conversion scheme is robust in preserving sharp edges, inhibiting edge shifting, and suppressing impulsive noise. In addition, the motion compensation interpolated HDMAC image sequence with the proposed I/F' conversion scheme shows 4-6 dB improvement in PSNR(Peak Signal-toNoise Ratio) compared with the interlaced one.
