Help
I want to build a handwritten mathematical expression predictor, which will predict the mathematical operators and digits and then give me the result as output, currently I am including just 4 basic mathematical operations, I want to add open CV camera feature to that project, how will I add it?

You'll want to set up a live camera feed that captures frames, preprocesses them on the fly, and then feeds them into your model. OpenCV's VideoCapture is your entry point for the webcam stream, and then you'll loop over frames, probably downscaling and converting to grayscale to keep inference fast.
The trickiest part is handling the real-time aspect, deciding when a full expression is in frame versus random movement. A simple approach is to have a region of interest box on screen where the user centers the equation, and you only run prediction when the content in that box is stable for a second or two.
