Support of (Key-)Point formats in CVAT

Hello everyone,

the issue itself is that, when I export annotations in COCO Format, points are not shown in the json, but polygons are. I have tried both creating a new task and only annotating points and also combining points and polygons, and neither of them exports the COCO Format with both instances.

Expected Behaviour

The expected behaviour is to be able to export the COCO Format with both points and polygons.

Current Behaviour

The current behaviour is that the COCO Format is not able to export points.

Possible Solution

It would just be a matter of implementing the points inside the COCO Format, so that they can be exported alongside the polygons.

Steps to Reproduce (for bugs)

1. Create a new task
2. Set a point
3. Export in COCO Format

Context

The project that I am actually working in requires both a combination of a mask and a keypoint inside of it, in the most important part of the object. Without the points, the goal cannot be accomplished.
