Architecture overview

architecture

  • The overall architecture of our model begins with training a shared grid in the frequency domain. This is followed by scale-specific low-pass filters designed to facilitate focus on crucial information. Subsequently, learnable frequency masks are applied to further refine frequency grids. To enhance visual clarity, the grid is shown as a basic square shape, even though it is fundamentally a vector matrix structure. The ⊙ represents element-wise multiplication.

Environment setup

  • conda create -n freqMipAA python=3.8
  • conda activate freqMipAA
  • pip install -r requirements.txt

Training

  • run the commands below at "/your/path/to/mipTensoRF" inside the docker container.

  • FreqMipAA on the multi-scale blender dataset.

bash ./scripts/multiscale_freqMipAA.sh
