Does CoreML object detection only support AABB (Axis-Aligned Bounding Boxes) or also OBB (Oriented Bounded Boxes)? If not, any way to do it using Apple frameworks?
Hello,
The types of bounding boxes available depend the on the model used for inference. Check out the object detection models here to see if they meet your needs.
If they don't then you'll need to find one that does and convert it to CoreML format with coremltools.
