Abstract: Common techniques such as frame repetition or linear interpolation for reconstructing skipped frames in temporally subsampled video sequence tend to introduce undesirable artifacts. A previously proposed technique, fast motion compensated temporal interpolation (FMCTI), can interpolate video frames in time domain with good interpolated image quality. However, the reconstructed frames tend to be blocky. In this paper, we proposed to incorporate a pixel-based motion classifier into FMCTI to solve the problem. The resulting technique, modified fast motion compensated temporal interpolation (MFMCTI), was found in simulation to give significantly reduced blocking artifacts.
