Is training haar cascade necessary?because iam trying to use the default frontal_face_default.xml file but is not working and i am using open cv2.4.13 and jdk 6 with it.

no, training your own cascade migt not be nessecary, and most likely, your existing cascade was simply not loaded due to a wrong path.

please check cascade.empty() after loading, rinse & repeat.

@saurabh, you must not use opencv's c-api (it's dead, no more maintained), but c++, and the tutorial is here

have you tried specifying the absolute path? It happened very often to me that things were not loaded properly if I used the relative path.
