It is not used for a new cascade. minSize: Minimum possible object size. Objects smaller than that are ignored. maxSize: Maximum possible object size. Objects larger than that are ignored. If faces are found, it returns the positions of detected faces as Rect(x,y,w,h). faces = face_cascade.detectMultiScale(gray, 1.3, 5)
