Hi Srinath, OpenCV provides us set of interesting tools which can be used to train classifiers based on our requirements. Some time ago I trained a classifier[1] and controlled drone in real time. This article explains[1] in a proper way how to train our own model using haar classifier based on Adaboost which OpenCV provide.
