Hi, I rather confuse how to use generalized hough transform with opencv python. When I set a template with a ROI of grayscale image, it shows error
Incorrect type of self (must be 'GeneralizedHough' or its derivative)
Here is my example code
alg = cv.GeneralizedHoughGuil()
# Simple create template with 1 channel black images with size 5x5
template = np.zeros((5,5))
alg.setTemplate(template)
