Abstract

In this paper, we propose a new motion vector smoothing based on the median filter for motion compensated frame rate up-conversion. The proposed method adaptively detects and corrects outliers in a motion vector field by considering neighboring motion vectors surrounding the current motion vector. Experiments show that the proposed method improves the average PSNR by up to 0.938 dB for all test sequences using the low hardware resource.
