Hello, am currently working with a face detection - recognition system, and currently am in the testing stage, but i am confused with Detection phase I have searched a lot, and came to many important points.

1. The detection i.e.

   face_cascade.detectMultiScale(gray, 1.05, 3,minSize=(20, 20), maxSize=(200,200))
   

how should i choose, scaling factor, and how is it important (i didn't totally understood what its useful for though i read a lot ), and how to choose min. neighbors and the window size to ensure that i will be able later on to recognize these faces.
