Senior Research Scientist
Bosch | UC Berkeley | ZJU

I am an AI Research Scientist at Bosch USA working on scalable 3D vision and graphics. My research focuses on geometric representation learning, differentiable rendering, and neural scene modeling.

I study how geometric structure shapes learned representations, seeking simple and principled formulations that generalize.

Good representations arise from simple underlying structure.

My early work explored robotic fabrication and the geometry of physical structures.

3DGEER: 3D Gaussian Rendering Made Exact and Efficient for Generic Cameras

Zixun Huang, Cho-Ying Wu, Yuliang Guo, Xinyu Huang, Liu Ren

We present 3DGEER, a formulation for exact and efficient Gaussian rendering under generic camera models, eliminating approximation errors introduced by splatting-based methods.

No Calibration, No Depth, No Problem: Cross-Sensor View Synthesis with 3D Consistency

Cho-Ying Wu, Zixun Huang, Xinyu Huang, Liu Ren

The work synthesizes view-aligned RGB-X pairs (thermal, NIR, SAR, Normal maps ...) from either raw sensor sequences or style maps to facilitate multi-modality learning. The work proposes a match-densify-consolidate framework to work from cross-modal image matching, guided densification, and consolidation in 3DGS.

NexusFlow: Unifying Disparate Tasks under Partial Supervision via Invertible Flow Networks

Fangzhou Lin, Yuping Wang, Yuliang Guo, Zixun Huang, Xinyu Huang, Haichong Zhang, Kazunori Yamada, Zhengzhong Tu, Liu Ren, Ziming Zhang

Can we learn across multiple tasks when Task 1 data is collected in region A and Task 2 data in region B? We introduce NexusFlow, a plug-and-play framework based on invertible flow networks that is effective for Partially Supervised Multi-Task Learning (PS-MTL) and the joint learning of diverse dense and sparse prediction tasks.

Robust 6DoF Pose Estimation Against Depth Noise and a Comprehensive Evaluation on a Mobile Dataset

Zixun Huang*, Keling Yao*, Seth Z. Zhao, Chuanyu Pan, Allen Y. Yang

We introduce DTTD-Mobile, a benchmark for evaluating 6DoF pose estimation under noisy mobile depth sensing. We further propose DTTD-Net, a Fourier-enhanced RGBD fusion architecture designed to improve robustness against low-quality depth inputs.
