Fast frame-rate up-conversion method for video enhancement

In this paper a new frame-rate up-conversion (FRUC) method is presented. To obtain an algorithm with a low level of complexity we used the block matching technique and fast subpixel motion estimation by Taylor series. Frame interpolation is made by combination of forward and backward prediction. Furthermore, for frames with a low temporal activity, the motion estimation is skipped and simple averaging of the previous and following frames makes the frame interpolation. Quality of the interpolated frames is compared according to PSNR results obtained for proposed and two more complex FRUC methods. Proposed method shows comparable results for all tested video sequences except for the sequences with a high level of motion.
