Google, Mountain View, CA 1 2 Video super-resolution (VSR) aims to convert low-resolution (LR) videos to high-resolution (HR) videos with high image quality [1]. It can be used for various video applications, such as streaming and conferencing, given low-bandwidth connectivity. Figure 2.8.1 shows a neural network (NN)-based VSR framework that comprises alignment and refinement stages
