I have seen multiple haarcascade xmls in opencv for face detection, eye detection , ear detection, Human body detection etc., But couldnt see proper documentation or explanation for these xmls.
For example in a application if I need to detect side faces which xml should I use and what are the parameters to be passed for detectMultiScale?
In some cases if I vary the parameters to detectMultiScale the false detections get reduced, but I did all the tests with trial and error method. I couldnt find any definite articles on explaining the use of each xml and parameters.
Can some one provide the documents on this if any, else some explanation on this would be grateful.
