BasicVSR

BasicVSR is a video super-resolution pipeline including optical flow and residual blocks. It adopts a typical bidirectional recurrent network. The upsampling module $U$ contains multiple pixel-shuffle and convolutions. In the Figure, red and blue colors represent the backward and forward propagations, respectively. The propagation branches contain only generic components. $S, W$, and $R$ refer to the flow estimation module, spatial warping module, and residual blocks, respectively.
