Object Recognition, what is possible and fast!

Hi Forum,
I have the problem that I need to recover from a photo an object.

I have for different objects all in all 5 categories and I need to check: In which category belongs the object of a new photo?
If I shoot now a photo, the program compare it to other images and then say:
"Bingo, this is the same object like in the database.
The database say for the old photo category 3, so it's is category 3."

The problem is now, how can I compare images if the objects are not exactly the same (pixel-for-pixel)?

But I have also some positive news:
The object will be in a limited area(30x30cm), with a good lightning (So if you have a red apple, next time the will have the same red) and the camera is always on the same position.

The only problem is, that the object could rotate. The photos will be made from above (bird's eye view).

You can use Deep Learning to train your data base on the fixed set of categories. Then use it to match new images. See books on Deep Learning or some forums such as https://www.pyimagesearch.com, https://www.learnopencv.com. See also OpenCV Deep learning tools. And https://opencv.org/courses/ and https://www.learnopencv.com/learn-pytorch/ and https://www.pyimagesearch.com/deep-lear ... thon-book/
