提出了一种新的高质量视频帧率上转换算法。在所提出的方案中，双向运动估计（ME）进行构造的运动矢量（MV）字段的帧内插。与传统的运动补偿插值（MCI）算法不同，该算法在插值帧中不产生任何重叠像素和空洞区域，因此可以利用重叠块运动补偿技术来减少块效应。与传统MCI方法相比，该算法在消费类产品上实现非常简单。计算机仿真结果表明，所提出的帧率上转换算法具有较高的视觉性能。
We propose a new frame rate up-conversion algorithm for high quality video. In the proposed scheme, bi-directional motion estimation (ME) is performed to construct the motion vector (MV) field for the frame to be interpolated. Unlike conventional motion-compensated interpolation (MCI) algorithms, the proposed technique does not produce any overlapped pixel and hole region in the interpolated frame, and thus can utilize the overlapped block motion compensation technique to reduce the blocking artifacts. The proposed algorithm is very simple to implement on consumer products when compared to conventional MCI methods. Computer simulation shows a high visual performance of the proposed frame rate up-conversion algorithm.
