Amazing! I have been following your tutorials and I got to learn a lot from them. There's a thing I want to implement, Realtime dynamic hand gesture recognition. I couldn't find a suitable source for that one over the internet. Although I could train your traffic signal model for getting a static solution for the same. If You could consider a dynamic project for one of your videos that'd be very helpful.

Hello, it's very nice. Your development seems to work very well with square and rectangular objects. Now, what happens if the object doesn't have that shape? For example, a wood shaving, a small piece of paper cut by hand, some shapeless pieces of plastic.
