Frame rate up-conversion using region-based optical flow

Frame rate up-conversion is widely used for converting between the standards and increasing the frame rate of low bit rate compression video conferences. The raster-based animation tweening algorithm can not be directly applied with frame rate up-conversion, because the crucial procedure of the algorithm, the mean shift-based image segmentation method, can not handle complex characteristics of a real world video image. In some case, the background and foreground may be merged into one segment. In this work, a synergistic image segmentation method is used according to the particular needs of a real world video image. The experimental results illustrate that higher quality in-between frames can be obtained by the proposed algorithm.
