A Frame Rate Up-Conversion Algorithm for 3-D Video

In this paper, we present an improved multi-pass true motion estimation algorithm for frame rate up-conversion. In the proposed motion estimation algorithm, the motion vectors of different objects which are parted with depth information will be refined respectively. Therefore, more accurate pixel-based motion vector can be obtained which causes the performance of Frame Rate Up-Conversion (FRUC). For overlapped regions, the motion vector can be chosen in candidates with depth information. Experimental results show that our proposed algorithm effectively enhances the overall quality of the frame rate up-converted video sequence, both subjectively and objectively, even with complex scenes and fast motion.
