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, motion compensated temporal interpolation (MCTI) can interpolate video frames in the time domain with good image quality at the cost of high computational requirement and substantial memory requirement. In this paper, we propose an algorithm called Unidirectional Motion Compensated Temporal Interpolation (UMCTI) which has lower computational and memory requirement but achieves considerably better peak-signal-to-noise ratio (PSNR). Several variants incorporating stationary block detection and/or overlapping motion compensation are also studied.
