摘要 介绍了如何进行整帧恢复的算法及相关理论,以提高图像恢复的速度与质量为目的,率先提出利用光流方程迭代求近似解,像素梯度信息插值恢复图像,缩小中值滤波窗口及使用次数,提出了一种更为快速、有效的整帧恢复算法FOFE。实验表明,由FOFE算法恢复的图像有更好的主观效果及客观质量。 This paper explained the thought of iterative optical flow formula to get solution and how to use gradient information to recover the lost image.As the aim to reduce the frequency and the window of median filter,this paper proposed a rapid and more effective error concealment algorithm which was named fast optical flow estimation(FOFE)algorithm.The experiments show that the result of the frame recovered by the FOFE algorithm has better subjective effect and objective quality.
