Scatter Ptychography

1 code implementation23 Mar 2022 Qian Huang, Zhipeng Dong, Yuzuru Takashima, Timothy J. Schulz, David J. Brady

Coherent illumination reflected by a remote target may be secondarily scattered by intermediate objects or materials.

SequentialPointNet: A strong frame-level parallel point cloud sequence network for 3D action recognition

1 code implementation16 Nov 2021 Xing Li, Qian Huang, Zhijian Wang, Zhenjie Hou, Tianjin Yang

The key to our approach is to divide the main modeling operations into frame-level units executed in parallel, which greatly improves the efficiency of modeling point cloud sequences. Moreover, we propose to flatten the point cloud sequence into a new point data type named hyperpoint sequence that preserves the complete spatial structure of each frame.

Edge Proposal Sets for Link Prediction

2 code implementations30 Jun 2021 Abhay Singh, Qian Huang, Sijia Linda Huang, Omkar Bhalerao, Horace He, Ser-Nam Lim, Austin R. Benson

Here, we demonstrate how simply adding a set of edges, which we call a \emph{proposal set}, to the graph as a pre-processing step can improve the performance of several link prediction algorithms.

Enhancing Adversarial Example Transferability with an Intermediate Level Attack

1 code implementation ICCV 2019 Qian Huang, Isay Katsman, Horace He, Zeqi Gu, Serge Belongie, Ser-Nam Lim

We show that we can select a layer of the source model to perturb without any knowledge of the target models while achieving high transferability.

Multispectral Image Intrinsic Decomposition via Subspace Constraint
