Got this error after I pressed 'z' key:

Do you have any idea?
@tungts1101 I will suggest you use
opencv-pythonversion3.4.*. You are facing this issue because you are using some higher version ofopencv-python.You can download the correct dependencies using
requirement.txtfile present in the repository.Hint: Use command
sudo pip install -r requirement.txtThat's work. But I think there's still something need to be done in order to eliminate noise in background.
Yes, that's an issue. You can take that up if you want.
Update this line...
From:
_, cont, hierarchy = cv2.findContours(thresh, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
To:
cont, hierarchy = cv2.findContours(thresh, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
That should fix the issue for CV 4.5
Thank you, it works
Hi, this is a great tutorial but my program will not recognize my hand. I hold it up in the proper position, but the green boxes remain. I know that my code is not wrong because I cross-referenced it with your github repo. Do you have any idea why this could be happening?
Hi @lukasswiss , I am glad that you liked my post.
Once you place your hand to cover all boxes, you have to press 'Z' key.
Amazing!
Thanks, Jeison!
Nice Amar, will be interested to see more from you here although I am not even a python coder!
Thanks @kataras , I am really happy that you liked it. 😊

Please name your sources at least!
sir can we do if we write 5 in air then the output as 5 will be in the output can we do like that

What is the use of this project? Problem statement?
It's awesome man! However, could you please tell me what kind of algorithm you used in calculating the farthest point?
Can we do this in MATLAB? If yes, how?
I have no idea about MATLAB, so can't say anything.
Wow this is super cool stuff!
Thanks @ben , glad you liked it!
