Video Super-Resolution (VSR) aims to reconstruct high-quality high-resolution (HR) videos from low-resolution (LR) inputs. Recent studies have explored diffusion models (DMs) for VSR by exploiting their generative priors to produce realistic details. However, the inherent randomness of diffusion models presents significant challenges for controlling content. In particular, current DM-based VSR met...Show More

This significantly...Show More
Huge progress has been made in LiDAR 3D semantic segmentation, but there are two under-explored imbalances on the radial axis: points are unevenly concentrated on the near side, and the distribution of foreground object instances is skewed to the near side. This leads the training of the model to favor semantics at the near side with the majority of points and object instances. Both the cylindrica...Show More
