If they were satisfied, standards conversion of arbitrary accuracy would be possible using suitable linear filters.  ...  It consists of two basic parts: temporal interpolation and spatial interpolation. A particular case is de-interlacing, which poses an inseparable spatio-temporal interpolation problem.  ...  Although there are restrictions, motion compensated interpolation techniques for field rate upconversion and de-interlacing provide the most advanced option.  ...

2021 Wireless Communications and Mobile Computing  
Motion-Compensated Frame Interpolation (MCFI) is one of the common temporal-domain tamper operations, and it is used to produce faked video frames for improving the visual qualities of video sequences.  ...  Experimental results show the proposed algorithm can improve the accuracy of BME and provide better objective and subjective interpolation qualities when compared with the traditional MVS algorithms.  ...  It can be used to increase the frame rate or temporal resolution of a video sequence, so it is also called Motion-Compensated Frame Rate Upconversion (MC-FRUC) [2, 3] .  ...
