Can ARKit recognize a round object?

Hi,


Is it possible to use ARKit to recognize objects in the camera view?


I have downloaded the ARKitImageRecognition demo, and it appears to be set up to recognize 2d pictures rather than objects.


The object I want to recognize is a flat plastic disc about 2" in diameter, with a fairly distinct blue color. I expect it to be facing the camera when I'm trying to detect it so it is effectively a 2d image, but since it is round, it might be against different backgrounds.


If I take a picture of the object and then trim the background out of the image with a photo editor (saving it as a PNG with a transparent background) will ARKit realize that I'm asking it to look for a round image instead of a rectangle? Or is there some other way to do this?


Thanks,

Frank
