Motion Vector Smoothing of Boundary of Moving Object for Frame Rate Up-Conversion

초록

This paper presents a motion vector smoothing method to increase the accuracy of the motion vector in the boundary of moving object. Existing motion vector smoothing methods cannot generate the accurate motion vectors in the boundary of moving object and it induces the block artifacts. To reduce these block artifacts, the proposed method detects the object boundary and extracts the moving region using the temporal information. Then, the boundary of moving object is extracted using the object boundary and the moving region information. Finally, the motion vector smoothing is performed to correct the falsely detected motion vector in the boundary of moving object. Experimental results demonstrate that the proposed method successfully increased the peak signal-to-noise ratio and the structural similarity index by up to 4.12 dB and 0.0626, respectively, compared to the benchmark methods.
