Video interpolation aims to generate a non-existent intermediate frame given the past and future frames. Many state-of-the-art methods achieve promising results by estimating the optical flow between the known frames and then generating the backward flows between the middle frame and the known frames. However. these methods usually suffer from the inaccuracy of estimated optical flows... https://www.roneverhart.com/Medline-Wheelchair-Arm-Trays-TRAY-ARM-WHEELCHAIR-ADJUSTABLE-LEFT-MDSR009636/
