Handcrafted solution example for the S23DR competition

• script.py - the main file, which is run by the competition space. It should produce submission.parquet as the result of the run.
• hoho.py - the file for parsing the dataset at the inference time. Do NOT change it.
• handcrafted_solution.py - contains the actual implementation of the algorithm
• other *.py files - helper i/o and visualization utilities
• packages/ - the directory to put python wheels for the custom packages you want to install and use.

Solution description

1. Using provided (but noisy) semantic segmentation called gestalt, it takes the centroids of the vertex classes - apex and eave_end_point and projects them to 3D using provided (also noisy) monocular depth.
2. The vertices are connected using the same segmentation, by checking for edges classes to be present - ['eave', 'ridge', 'rake', 'valley'].
3. All the "per-image" vertex predictions are merged in 3D space if their distance is less than threshold.
4. All vertices, which have zero connections, are removed.
