Semantically annotated traffic lights for the Cityscapes dataset.
Run the apply_changes.py script on top of your dataset copy (setting the --dry-run-flag will not modify anything):
python3 apply_changeset.py /path/to/cityscapes ~/Downloads/changes_dusseldorf.json
marginalize labels for a single-class object detector:
Adapt my_marginalization in marginalize.py to your liking. Then run
python3 marginalize.py /path/to/updated/cityscapes /tmp/my/marginalized/labels
