摘要

提出了一种基于金字塔结构的分层运动补偿帧率转换(HMC-FRC)算法，用于高质量视频重建。具有不同帧率的图像之间的转换会导致运动抖动和移动物体边界附近的模糊。为了减少视频质量的下降，该算法在高斯/拉普拉斯图像金字塔的每一级执行运动估计(ME)和运动补偿帧率上转换。在实验中，视频序列的帧率被上转换为原来的2倍。多个测试序列的实验证明了该算法的有效性。

Hierarchical motion compensated frame rate up-conversion based on the Gaussian/Laplacian pyramid

We present a hierarchical motion compensated frame rate conversion (HMC-FRC) algorithm based on the pyramid structure for high-quality video reconstruction. The conversion between images having different frame rates causes motion jitter and blurring near moving object boundaries. To reduce degradation in video quality, the proposed algorithm performs motion estimation (ME) and motion compensated frame rate up-conversion at each level of the Gaussian/Laplacian image pyramid. In experiments, the frame rate of the video sequence is up-converted by a factor of two. Experiments with several test sequences show the effectiveness of the proposed algorithm.
