What is the easiest way to recognise gestures in OpenCV?
Can you explain how Haar cascades work?
Haar cascades work by training a classifier on positive and negative images. In the case of hand gesture recognition, you would first need to train a classifier on images of hands in various positions and orientations (positive images), as well as images that don't contain hands (negative images). Once the classifier has been trained, you can use it to detect hands in new images.
