In this paper, we propose a frame rate upconversion algorithm using the weighted-adaptive motion-compensated interpolation (WAMCI) that reduces the block artifacts due to the failure of motion estimation and block-based processing. The proposed method is based on the interpolation scheme by weighted sum of multiple motion-compensated interpolation (MCI) images. Also, in the proposed method, the block artifacts on the block boundaries are reduced by applying a technique similar to the overlapped block motion compensation (OBMC). To reduce the blurring of overlapping processing, the proposed method uses the motion analysis to determine the type of motion and applies the OBMC adaptively. Experimental results indicate good performance of the proposed scheme with significantly reduced block artifacts.
