OVERLAPPED BLOCK MOTION COMPENSATION FOR FRAME RATE UP CONVERSION

Suk Kim, Taeuk Jeong, Chulhee Lee

Abstract

Recently, motion compensated interpolation methods are used to generate new frames in the frame rate up conversion. However, they often yield undesirable blocking artifacts due to inaccurate motion estimation. In order to mitigate these artifacts, we propose a new motion-compensated frame rate up conversion algorithm with overlapped block motion estimation. The new interpolated frame is obtained by overlapped block motion compensation of multiple motion estimation between the current and previous frames. Experimental results show the proposed method produces better perceptual quality and outperforms conventional motion-compensated methods in terms of PSNR.
