neuralhdhair's Introduction

NeuralHDHair

The source code of the networks for our paper "NeuralHDHair: Automatic High-fidelity Hair Modeling from a Single Image Using Implicit Neural Representations" (CVPR2022)

Pipeline

Prerequisites

Linux
Python 3.8
Pytorch 1.8.1
NVIDIA GPU + CUDA 11.1

Train

1.Train Coarse module

python main.py --name=yourname --model_name=HairSpatNet --blur_ori --no_use_depth --no_use_L --gpu_ids=0 --batch_size=1

2.Train Global module

python main.py --name=yourname --model_name=HairModelingHD --blur_ori --no_use_depth  --gpu_ids=0 --batch_size=1 --pretrain_path=pretrain_model_path

3.Train GrowingNet

python main.py --name=yourname --model_name=GrowingNet  --batch_size=1 --sd_per_batch=800 --pt_per_strand 72

Tips

1.Data, some data processing and rendering code do not have permissions and cannot open source temporarily.

2.Use high-quality images as much as possible, the quality of reconstruction depends largely on the quality of generated orientation map.

3.The hair should be aligned with the bust as much as possible, you may need the face alignment algorithm to calculate the affine transformation.(data/Train_input/DB1 contains standard input samples)
