Nice, thank you for the upload and thank you for clarifying that small objects are not labeled, that explains it. I was suprised because other images do contain rather small labels for traffic lights or even cars, but I guess it's always in the eyes of the person who labels the data.
I think you did an amazing amount of work and huge improvements over the original, have you considered contributing the changes back upstream?
I plan to. They use a custom CSV format that my labeling tool can't work with so I converted everything to VOC XML. I need to write a script to convert back to their format to submit a PR.
Not sure if they'll accept the PR though; the original data had a "visualization link" back to the labeling company on each line which I can't reproduce.
