📜 Fillerbuster: Multi-View Scene Completion for Casual Captures

Fillerbuster is a unified multi-view diffusion model for solving a variety of scene completion tasks. We trained Fillerbuster from scratch. Here we provide training code and inference code for completing scenes.

Project Page @ https://ethanweber.me/fillerbuster

We provide training code and inference code, but we do not provide training data. However, this codebase should be easy to adapt to multi-view datasets!

Set Up Environment

1. Create and activate the fillerbuster environment:

   conda create -n fillerbuster python=3.10 -y
   conda activate fillerbuster

2. Install dependencies and the repo

   pip install torch torchvision --index-url https://download.pytorch.org/whl/124
   pip install -e .

Download Weights and Inference Data

1. Download Fillerbuster weights from this folder and place inside a checkpoints folder.

2. Download CLIP weights into the checkpoints folder.

   git lfs install
   cd checkpoints
   git clone https://huggingface.co/openai/clip-vit-large-patch14

3. Download casual capture data from other works: namely, LERF, Nerfbusters, NeRFiller, and Nerfstudio datasets from this convenient all-on-one folder. Download and extract the data.zip file to create a data folder as specified in their README.txt.

4. Download our videos and place them in data/videos.

Demo

We provide demo.ipynb as a minimal example to run inference with our model.

Experiments

If you want more details on experiments, see EXPERIMENTS.md. Here we provide a minimal set of commands to get started!

1. "Completing Casually Captured Scenes" (Nerfbusters data)

   ns-train fillerbuster --data data/nerfbusters-dataset/picnic --output-dir outputs/nerfstudio-outputs nerfstudio-data --eval-mode filename

2. "Uncalibrated Scene Completion" (video data)

   python fillerbuster/scripts/run_uncalibrated_scene_completion.py --data data/videos/couch.mov --output-dir outputs/uncalibrated-outputs

3. "Completing Masked 3D Regions" (NeRFiller data)

   ns-train fillerbuster --data data/nerfiller-dataset/billiards --output-dir outputs/nerfstudio-outputs --pipeline.inpainter nerfiller --pipeline.dilate-iters 5 --pipeline.context-size 32 --pipeline.densify-num 0 --pipeline.anchor-rotation-num 0 --pipeline.anchor-vertical-num 0

Training

This section is not yet operational. Check back soon!

We are releasing our training code. See TRAIN.md for more details. We are not providing the training data.
