This pull request introduces several improvements to the documentation and visualization utilities, as well as a new function for error visualization in the codebase. The main changes include updating command-line usage examples for visualization tools across documentation files, adding a new utility for error-to-color mapping, and minor enhancements for dataset handling and user guidance.

Documentation and Usage Updates:

  • Updated all visualization command-line examples in README.md, tools/README.md, and output messages in src/trainer.py to use subcommands such as vis, vector, check, and error for tools/visualization.py, improving clarity and consistency for users. Added tips for qualitative comparison and quick screenshot saving. [1] [2] [3]
  • Added instructions in tools/README.md for quickly reading .h5 files using the new tools/read_h5.py script.

Visualization and Utility Enhancements:

  • Introduced a new function error_to_color in src/utils/mics.py to convert flow error magnitudes into RGB color visualizations, supporting "jet" and "hot" color maps for enhanced error analysis.

Dataset and Data Handling:

  • Added lidar_center to the list of keys loaded from the dataset in src/dataset.py, ensuring this data is available for downstream processing.

Other Improvements:

  • Commented out a deprecated submission command in README.md to prevent confusion.

When testing error mode on datasets that don't have flow annotations for every frame (nuScenes, TruckScenes), it errors due to missing 'flow' key
