Abstract :
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.
