Key-Frame-based Video Super-Resolution (K = 15)

Key-Frame-based Video Super-Resolution is a sub-task of Video Super-Resolution, where, in addition to the low-resolution frames, high-resolution ground-truth frames for every Kth input frame are also provided as inputs to the model. For example, if [LR-frame-1, LR-frame-2, LR-frame-3, ..., LR-frame-100] is the sequence of low-resolution frames to be upscaled, the Key-Frame-based Video Super-Resolution (K = 15) model is also provided with the high-resolution frames [HR-frame-1, HR-frame-16, ..., HR-frame-91] . Key-frames are excluded when measuring the evaluation metrics.
