Greetings,

So I've tried CVAT for quite some time. And I decided to try to create a custom dataset with the cityscapes format dataset using CVAT on https://app.cvat.ai/ for my next project.
The datasets provided from https://cityscapes-dataset.com included the polygon .JSON file for each annotated image (as in the picture below),

.

But when I tried to export my task into Cityscapes 1.0 format on cvat.ai, it doesn't show the .json file.

Is it the way cityscapes-dataset format worked for custom datasets, or is there something else that I missed?
I appreciate any assistance.
Thank you know advance.

Best Regards,
Aldy.

@zhiltsov-max Does Cityscapes format have the .json file?

[zhiltsov-max]

Hi. Yes, I see, there are also polygon jsons in Cityscapes, but our implementation only supports images in this format. As a workaround, please check if you can use COCO jsons with polygons.

[aldyhelnawan]

Hi, thank you for your assistance.
I see. I will try to use the COCO JSONs for the polygons, see will it fit for my current project.
Will the JSON polygon file on cityscapes format be available in CVAT in the future?
Thank you in advance.

Glad to help. I can't make promises on the future plans, but if this problem with Cityscapes is important for our community, we can prioritize it for future releases, and fix it. We are also open for community PR on this topic.
