Abstract

This paper proposed a low complexity halo reduction method for motion compensated frame interpolation which bases on only two successive frames. An improved forward and backward jointing motion estimation method that features a faster convergence speed is utilized to produce the motion vector fields of the original frames. These motion vector fields are retimed to the to-be-interpolated frame to calculate the motion vector field for interpolation and to get the coarse location of the new exposed areas. Through analyzing the relationship of the adjacent motion vectors, two general equations are generated for the covered and uncovered blocks, and occlusion areas are further refined. Finally, unidirectional interpolation and bi-directional interpolation are combined to avoid the halos and block artifacts. Experimental results show that the proposed algorithm achieves much better image quality than that without halo reduction processing.
