How is the repository structured?

• The codebase is located in the agg_utils (python scripts) and notebooks folder.
• Additional details can be found in markdown files in the details folder.
• Supplementary gifs are located in the gifs folder.
• See notebooks README for the more details.
  • The 0.* notebooks contain data parsing and figure generation.
  • The 1.* notebooks perform the core experiments (visual representativeness and visual stability).
  • The varia_* notebooks perform further analysis: OR-conv, toolkit comparison, and M4 pixel-perfect nuances.
• The animations folder contains html animations, which allow to inspect the phenomena in more detail.
