Mouse Control with hand gestures

10 views (last 30 days)
Hello,
I have this code that is able to count my fingers from 1-5 and the mouse commands that go with each number.
The mouse commands aren't working and I have no idea why. The camera is connected properly and the gestures and recognized properly as well.
Any help would be appreciated.

Here's the updated code, it works now.
We changed it so the size of the matrix is used rather than the string.
