Is Bounding Box Export Available in CoralNet

[Dimas Auliamukti]

Hello,
I would like to ask whether CoralNet allows annotations to be downloaded in bounding box format instead of point annotations.

If not, does anyone know a proper method to convert point annotations into bounding boxes?

I would also really appreciate it if there are any scientific studies or research papers that support or describe this conversion process.

Thank you in advance!

You can create bounding boxes for the points artificially, but this isn't ideal because it's not tightly fitted around the object. CoralNet uses Patches, which is just an area (224x224) center on the point. A bounding box specifically represents in box tightly fitting the object, which is different from a patch. If you're trying to do Object Detection with CoralNet annotations, this might be of use, but really it's going to be difficult to go from points / patches to bounding boxes.

You can try to create a bounding box using SAM, using the point as a prompt, but a single point is very ambiguous and will likely not work on every occasion.
