SemAffiNet: Semantic-Affine Transformation for Point Cloud Segmentation

1 code implementation26 May 2022 Ziyi Wang, Yongming Rao, Xumin Yu, Jie zhou, Jiwen Lu

Conventional point cloud semantic segmentation methods usually employ an encoder-decoder architecture, where mid-level features are locally aggregated to extract geometric information.

FineDiving: A Fine-grained Dataset for Procedure-aware Action Quality Assessment

1 code implementation7 Apr 2022 Jinglin Xu, Yongming Rao, Xumin Yu, Guangyi Chen, Jie zhou, Jiwen Lu

Most existing action quality assessment methods rely on the deep features of an entire video to predict the score, which is less reliable due to the non-transparent inference process and poor interpretability.

PoinTr: Diverse Point Cloud Completion with Geometry-Aware Transformers

1 code implementation ICCV 2021 Xumin Yu, Yongming Rao, Ziyi Wang, Zuyan Liu, Jiwen Lu, Jie zhou

In this paper, we present a new method that reformulates point cloud completion as a set-to-set translation problem and design a new model, called PoinTr that adopts a transformer encoder-decoder architecture for point cloud completion.
