CityScapes labels: Number of classes

[flpgrz]

Hello,

I'm going to do a fine-tuning of your model for a segmentation task.
I would like to keep the same 19 semantic classes that you used for trainining the model on the CityScapes dataset.

Could you please tell me how you pre-processed the CityScapes labels in order to obtain the 19 classes?

Thanks a lot.
Filippo
