[CVPR 2020] 3D Photography using Context-aware Layered Depth Inpainting
[Paper] [Project Website] [Google Colab]
We propose a method for converting a single RGB-D input image into a 3D photo, i.e., a multi-layer representation for novel view synthesis that contains hallucinated color and depth structures in regions occluded in the original view. We use a Layered Depth Image with explicit pixel connectivity as underlying representation, and present a learning-based inpainting model that iteratively synthesizes new local color-and-depth content into the occluded region in a spatial context-aware manner. The resulting 3D photos can be efficiently rendered with motion parallax using standard graphics engines. We validate the effectiveness of our method on a wide range of challenging everyday scenes and show fewer artifacts when compared with the state-of-the-arts.

Prerequisites
- Linux (tested on Ubuntu 18.04.4 LTS)
- Anaconda
- Python 3.7 (tested on 3.7.4)
- PyTorch 1.4.0 (tested on 1.4.0 for execution)
and the Python dependencies listed in requirements.txt
- To get started, please run the following commands:
conda create -n 3DP python=3.7 anaconda conda activate 3DP pip install -r requirements.txt conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit==10.1.243 -c pytorch - Next, please download the model weight using the following command:
chmod +x download.sh ./download.sh
Quick start
Please follow the instructions in this section.
This should allow to execute our results.
For more detailed instructions, please refer to DOCUMENTATION.md.
Execute
- Put
.jpgfiles (e.g., test.jpg) into theimagefolder.- E.g.,
image/moon.jpg
- E.g.,
- Run the following command
python main.py --config argument.yml- Note: The 3D photo generation process usually takes about 2-3 minutes depending on the available computing resources.
- The results are stored in the following directories:
- Corresponding depth map estimated by MiDaS
- E.g.
depth/moon.npy,depth/moon.png - User could edit
depth/moon.pngmanually.- Remember to set the following two flags as listed below if user wants to use manually edited
depth/moon.pngas input for 3D Photo.depth_format: '.png'require_midas: False
- Remember to set the following two flags as listed below if user wants to use manually edited
- E.g.
- Inpainted 3D mesh (Optional: User need to switch on the flag
save_ply)- E.g.
mesh/moon.ply
- E.g.
- Rendered videos with zoom-in motion
- E.g.
video/moon_zoom-in.mp4
- E.g.
- Rendered videos with swing motion
- E.g.
video/moon_swing.mp4
- E.g.
- Rendered videos with circle motion
- E.g.
video/moon_circle.mp4
- E.g.
- Rendered videos with dolly zoom-in effect
- E.g.
video/moon_dolly-zoom-in.mp4 - Note: We assume that the object of focus is located at the center of the image.
- E.g.
- Corresponding depth map estimated by MiDaS
- (Optional) If you want to change the default configuration. Please read
DOCUMENTATION.mdand modifiedargument.yml.
