This repository contains the official implementation of the ECCV2022 paper:
Object-Compositional Neural Implicit Surfaces.
Qianyi Wu, Xian Liu, Yuedong Chen, Kejie Li, Chuanxia Zheng, Jianfei Cai, Jianmin Zheng.
The paper introduces ObjectSDF: a volume rendering framework for object-compositional implicit neural surfaces, allowing learning high fidelity geometry of each object from a sparse set of input images and the corresponding semantic segmentation maps.
The code is compatible with Python 3.9 and Pytorch 1.10.1. In addition, the following packages are required: numpy, pyhocon, plotly, scikit-image, trimesh, imageio, opencv, torchvision.
You can create an anaconda environment called objsdf with the required dependencies by running:
conda env create -f environment.yml
conda activate objsdf
We provide the installation guidance to use our code in the Toydesk dataset. First, you need to download Toydesk dataset and put it in the './data' folder. Then
cd data
bash process_toydesk.sh
We require the RGB images with the corresponding semantic segmentation map for model training. After running the above script, you will get the corresponding file for two desk scenes.
For example, if you would like to train ObjectSDF on Toydesk 2, please run:
cd ./code
python training/exp_runner.py --conf confs/toydesk2.conf --train_type objsdf
