UPS-HSG: Uncalibrated Photometric Stereo Based on Adaptive Hybrid Spherical Gaussian

This repository will host the official implementation of UPS-HSG, a self-supervised uncalibrated photometric stereo network.
The code and pretrained models are currently being prepared for release.

Status

🚧 Coming Soon
We are cleaning up the source code, organizing experiments, and preparing documentation for public release.

Planned Release

The open-source version is expected to include:

• Full training and inference code
• Pretrained weights
• Example datasets and usage instructions
• Scripts for evaluation and reproduction of paper results
