Abstract

In this paper, we propose a frame rate upconversion (FRUC) algorithm to increase the temporal resolution of video sequences at the decoder side. First, the proposed algorithm segments a frame into several objects. Then, perspective transforms are used to motion-compensate each object, while the translational block matching algorithm (BMA) is applied to the background. Furthermore, the overlapped block motion compensation (OBMC) technique is used to reduce blocking artifacts in boundary blocks. Experimental results show that the proposed algorithm provides better performance than the conventional approach.
