I had some success with pictures of sofas from a top view, but a lot came out as complete nonsense like "nail" or "light bulb". Seems on at least some patterns

I had some success with pictures of sofas from a top view, but a lot came out as complete nonsense like "nail" or "light bulb". Seems on at least some patterns it is trained to view things in a particular orientation that you would normally see them in. I imagine that if it did exhaustive rotation searches on a lot of objects the results would often be completely incorrect.
