I am using java library of open cv 2.4.7. I don't know how to use its FaceRecognizer class. when I looked at the definition of this class I found this.

Ptr_FaceRecognizer createEigenFaceRecognizer(int num_components = 0, double threshold = DBL_MAX)

Return type 'Ptr_FaceRecognizer' is not supported, skipping the function.

is there any other method to use this algorithm? As I am very new in the field of open cv so Please suggest the way to perform face recognition by using open cv java library.

Did you actually tried googling for a solution? Just adding java - opencv - facerecognizer gives me about 100 possible tutorials that all work decently...

sorry, dear, that's a (known) bug.

atm the java wrapper can't handle Ptr<something> types (in c++) properly and thus just skips them (as your msg says there).

so there's no native / JNI code for cv::createLBPHFaceRecognizer() and friends

(msg is from opencv\build\modules\java\contrib.txt, right ?)

feel free to append to the issue above.
