| Research Type | Experimental | We further demonstrate through experiments that the increased diversity in deformable alignment yields better-aligned features, and hence significantly improves the quality of video super-resolution output. Experiments show that our loss successfully avoids the overflow of offsets and alleviates the instability problem of deformable alignment. We conduct experiments to reveal the connections and differences between deformable and flow-based alignments in video SR. |
