Abstract
A novel method of using optical flow algorithm that maximizes the benefit of optical flow synthetic frames while minimizing the associated computation cost is provided. When using optical flow to produce synthetic frames between two actual/recorded frames, the method computes a set of estimates of optical flows (or a flow estimate) between the two frames. These flow estimates are then used to compute all synthetic frames that are needed between the two actual frames by interpolation, which creates each synthetic frame based on its temporal distances from the pair of actual frames.
