Hi, i am trying to find the right way of how to detect different objects in one picture with several classifiers simultaneosly. I know how to detect face on the picture with "lbpcascade_frontalface.xml" default opencv classifier, but if i want to simultaneosly detect also "dogs.xml", "cats.xml" and so on... what is the best right way to do it? I am using C++ (opencv v 2.4.1). thank you for replies...
