Huan LEI

I am now funded by AIML Adelaide to continue my research on computational mesh modelling. I was a Research Fellow at the Australian National University in 2022, working on geometric data processing with Hongdong Li. I received my Doctorate from the University of Western Australia where I was advised by Ajmal Mian and Naveed Akhtar. My PhD was funded by the Research Training Program of Australian Government.

Research Interests

I'm interested in neural fields for surface reconstruction, geometric deep learning for 3D Vision+Graphics, self-supervised learning, computational geometry.

prl Mesh Convolution with Continuous Filters for 3D Surface Parsing
Huan Lei, Naveed Akhtar, Mubarak Shah, Ajmal Mian.
TNNLS, 2023. Project/Code/Bibtex

Picasso and PicassoNet++ for deep learning over heterogeneous 3D meshes. We formulate the continuous filters for mesh convolution using spherical harmonics as orthonormal basis.

prl CircNet: Meshing 3D Point Clouds with Circumcenter Detection
Huan Lei, Ruitao Leng, Liang Zheng, Hongdong Li.
ICLR, 2023. Project/Code/Bibtex

By exploiting the duality between a triangle and its circumcenter, we propose to triangulates 3D point clouds into manifold meshes using a graph neural network, named CircNet. The network detects circumcenters and recovers vertex triplets of each triangle face, reconstructing a primitive mesh. Standard post-processing is then applied to convert the primitive mesh into a manifold surface.

prl Picasso: A CUDA-based Library for Deep Learning over 3D Meshes
Huan Lei, Naveed Akhtar, Ajmal Mian.
CVPR 2021. Project/Code/Bibtex

The preliminary Picasso for geometric deep learning over 3D meshes. Please refer to our TNNLS2023 work for the latest Pytorch codes.

prl SegGCN: Efficient 3D Point Cloud Segmentation with Fuzzy Spherical Kernel
Huan LEI, Naveed Akhtar, Ajmal Mian.
CVPR 2020. Code/Bibtex

Fuzzy modelling makes convolutions robust to varying densities of point clouds.

prl Spherical Kernel for Efficient Graph Convolution on 3D Point Clouds
Huan Lei, Naveed Akhtar, Ajmal Mian.
TPAMI, Mar 2020. Code/Bibtex
prl Octree guided CNN with Spherical Kernels for 3D Point Clouds
Huan Lei, Naveed Akhtar, Ajmal Mian.
CVPR 2019. Bibtex
prl Geometric Deep Learning for 3D Data
