Abstract :
In this paper, we propose a motion vector smoothing scheme for motion-compensated frame rate up-conversion. The proposed motion vector smoothing consists of three steps which are outlier detection, outlier correction, and motion vector refinement steps. The proposed method enhances the image quality of the interpolated frame by up to 0.88 dB, and the visual result of the proposed method is better than those of the benchmark methods.
