Code:

    // setup landmarks detector
    Facemark fm = Face.createFacemarkKazemi();
    fm.loadModel("C:\\Users\\Jayashree\\Desktop\\Faces_Oct18th\\model\\flandmark_model.dat");

Exceptions as below:

Exception in thread "main" java.lang.Exception: std::exception: bad allocation

bad allocation means: you're out of memory ! (huge model, ~97mb)

watch your resources in the Task-manager
try to assign more memory to your java process (-Xmx)
check, if you built 32bit opencv libs (4gb limit), if so, try with 64bit
the LBF model is only half the size (and also more precise, imho)

I made Java vm args to 2056 in eclipse but still no luck.

Code changed to createFacemarkLBF() :

    Facemark fm = Face.createFacemarkLBF();//.createFacemarkKazemi();
    fm.loadModel("C:\\Users\\Jayashree\\Desktop\\Faces_Oct18th\\model\\flandmark_model.dat");

Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: OpenCV(3.4.3) C:\opencv343\opencv-3.4.3\modules\core\src\persistence_c.cpp:388: error: (-49:Unknown error code -49) Input file is empty in function 'cvOpenFileStorage'

Also where to make changes to build opencv libs to 64 bit
