BSRT: Improving Burst Super-Resolution with Swin Transformer and Flow-Guided Deformable Alignment
Ziwei Luo,Youwei Li,Shen Cheng,Lei Yu,Qi Wu,Zhihong Wen,Haoqiang Fan,Jian Sun,Shuaicheng Liu +8 more
TL;DR: This work combines optical flows and deformable convolutions, hence the BSRT can handle misalignment and aggregate the potential texture information in multi-frames more efficiently and wins the championship in the NTIRE2022 Burst Super-Resolution Challenge.
Proceedings ArticleDOI
Dynamic Grained Encoder for Vision Transformers
TL;DR: A Dynamic Grained Encoder for vision transformers is proposed, which can adaptively assign a suitable number of queries to each spatial region and achieves a fine-grained representation in discriminative regions while keeping high efficiency.

Point Integral Method for Solving Poisson-type Equations on Manifolds from Point Clouds with Convergence Guarantees
Zhen Li,Zuoqiang Shi,Jian Sun +2 more
TL;DR: In this article, a point integral method (PIM) is proposed to solve the Poisson-type equations from point clouds with convergence guarantees, where the key idea is to derive the integral equations which approximates the poisson type equations and contains no derivatives but only the values of the unknown function.
