摘要 提出了一种基于同奇偶运动检测的运动补偿算法。基于同奇偶的运动检测,充分利用了场的同奇偶特性,能提高运动检测的准确性。在运动检测过程中,通过设定门限,寻找到更合理的最佳匹配块(OMB),进而得到更精确的运动矢量。同时,改进的基于边界的行平均算法(E-ELA)也在算法中合理使用。实验结果显示,该算法能够得到更好的峰值信噪比(PSNR),也有更好的显示效果。 In this paper,a motion compensated de-interlacing algorithm based on same-parity motion detection is presented.The same-parity motion detection makes full use of the parity property of field,and it could improve the accuracy of motion detection.A threshold is set in the motion detection to find more proper Optimal Matching Block(OMB),then more accurate motion vectors could be found.The Enhanced Edge-based Line Average(E-ELA) is also used in the algorithm.The experimental results show that the proposed algorithm can get better Peak Signal-to-Noise Ratio(PSNR) than previous de-interlacing methods.
