Refinement of Hair Geometry by Strand Integration,

Computer Graphics Forum (PG2023)
This repository contains the following implementations:
- Strand Integration: The official implementation of our paper "Refinement of Hair Geometry by Strand Integration" (PG2023).
- LPMVS: The unofficial implementation of LPMVS (Line-based PatchMatch MVS) proposed in the paper "Strand-accurate Multi-view Hair Capture" (CVPR2019). And we also provide the implementation of 3D line filtering.
This repository contains small-scale multi-view images of straight hair for debugging our code. This data is identical to the data used in our paper except that it is resized to 1/10. You can see it in data/straight_s.
You can download the full-scale multi-view images from release page.
Our code requires to install the our custom Python extension implemented in C++. Please build and install it before running our code.
cd cpp_ext
pip install .For more details, please refer to cpp_ext.
# LPMVS
python run_lpmvs.py data/straight_s -o result/lpmvs/straight_s
# Estimate a 3D line map for each view from multi-view images.
# Run 3D line filtering (for LPMVS)
python run_line_filtering.py result/lpmvs/straight_s result/merged_ply/lpmvs/straight_s.ply
# Merge the 3D line maps into a single point cloud file.
# 3D line consistency map
python run_consistency_map.py result/lpmvs/straight_s -o result/consistency/straight_s
# Generate a 3D line consistency map described in Subsection 3.5 in our paper.
# Strand Integration
python run_strand_integration.py result/lpmvs/straight_s --consistency result/consistency/straight_s -o result/si/straight_s --views 5 --imshow
# This will only apply for view 5. You can run for all views by removing the --views option.
# 3D line filtering (for Strand Integration)
python run_line_filtering.py result/si/straight_s result/merged_ply/si/straight_s.ply
# After running all views, you can merge the results same as the above process.@article{maeda2023refinement,
