Issue while Executing Application

In CPU Mode

When we disable GPU Mode and run through CPU Mode the face detection is working ..

int flag = CV_HAAR_DO_ROUGH_SEARCH|CV_HAAR_SCALE_IMAGE;
 this->face_detector_cpu.detectMultiScale(gray, faces_tmp, 1.2, 1, flag,
                                                       cv::Size(param.minFaceSize,  param.minFaceSize),
                                                       cv::Size(param.maxFaceSize,  param.maxFaceSize));

FPS: Face Detection is detecting with less FPS

In GPU Mode

When we disable the GPU mode and executing our Application the face detection is working fine

But if we enable the GPU mode the face detection is not working its getting freezed in detectMultiScale function

The following is the code for the reference

FaceDetector::getInstance().detect(frame, faces_haar, faceParam, FaceDetectionType == "HAAR",  enable_gpu, scale);

this->face_detector_gpu->detectMultiScale(im_gpu, faces_gpu);
