2013-04-09 23:54:58 -0600 commented answer Unhandled exception after run in face detection

hi, i do all things you suggest me. but unfortunately the problem is exist. First-chance exception at 0x559c61cf in newfaceDetection.exe: 0xC0000005: Access violation writing location 0x00000000. Unhandled exception at 0x559c61cf in newfaceDetection.exe: 0xC0000005: Access violation writing location 0x00000000.
2013-04-09 12:43:57 -0600 asked a question Unhandled exception after run in face detection

hi all,

i am using the following code for face detection:

#include "opencv2/objdetect/objdetect.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"

#include <iostream>
#include <stdio.h>

using namespace std;
using namespace cv;

 /** Function Headers */
 void detectAndDisplay( Mat frame );

 /** Global variables */
 String face_cascade_name = "haarcascade_frontalface_alt.xml";
 String eyes_cascade_name = "haarcascade_eye_tree_eyeglasses.xml";
 CascadeClassifier face_cascade;
 CascadeClassifier eyes_cascade;
 string window_name = "Capture - Face detection";
 RNG rng(12345);

 /** @function main */
 int main( int argc, const char** argv )
 {
   CvCapture* capture;
   Mat frame;

   //-- 1. Load the cascades
   if( !face_cascade.load( "D:/Visual Studio 2010/Projects/newfaceDetection/haarcascade_frontalface_alt.xml" ) ){ printf("--(!)Error loading\n"); return -1; }
   if( !eyes_cascade.load( "D:/Visual Studio 2010/Projects/newfaceDetection/haarcascade_eye_tree_eyeglasses.xml" ) ){ printf("--(!)Error loading\n"); return -1; }

   frame=imread("d:/1.jpg");
   imshow( "test image", frame );
   if( !frame.empty() )
       { detectAndDisplay( frame ); }
   cvWaitKey(0);

   return 0;
 }

/** @function detectAndDisplay */
void detectAndDisplay( Mat frame )
{
  std::vector<Rect> faces;
    //Mat faces;
  Mat frame_gray;

  cvtColor( frame, frame_gray, CV_BGR2GRAY );
  equalizeHist( frame_gray, frame_gray );

  //-- Detect faces
  face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(40, 40) );

  for( int i = 0; i < faces.size(); i++ )
  {
    Point center( faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5 );
    ellipse( frame, center, Size( faces[i].width*0.5, faces[i].height*0.5), 0, 0, 360, Scalar( 255, 0, 255 ), 4, 8, 0 );

    Mat faceROI = frame_gray( faces[i] );
    std::vector<Rect> eyes;

    //-- In each face, detect eyes
    eyes_cascade.detectMultiScale( faceROI, eyes, 1.1, 2, 0 |CV_HAAR_SCALE_IMAGE, Size(30, 30) );

    for( int j = 0; j < eyes.size(); j++ )
     {
       Point center( faces[i].x + eyes[j].x + eyes[j].width*0.5, faces[i].y + eyes[j].y + eyes[j].height*0.5 );
       int radius = cvRound( (eyes[j].width + eyes[j].height)*0.25 );
       circle( frame, center, radius, Scalar( 255, 0, 0 ), 4, 8, 0 );
     }
  }
  //-- Show what you got
  imshow( window_name, frame );
 }

after I run the code i get the following error 

(First-chance exception at 0x0fd761cf in newfaceDetection.exe: 0xC0000005: Access violation writing location 0x00000000. Unhandled exception at 0x0fd761cf in newfaceDetection.exe: 0xC0000005: Access violation writing location 0x00000000.)

if I comment out the following line

( `face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(40, 40) );`  )

the program will run without any errors but the face detection doesn't work. It will only show the image.

What do i need to do? I have studied many resources like previous forum questions but I don't reach any positive result yet. please help me , thanks in advance

I have this problem yet, //face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) ); when i comment program runs but face isn't detected , when i remove comment ,at first program runs but after several seconds ,it shows error in dialog box , (break,continue , ) and faceRecognition.exe: Native' has exited with code -1073741510 (0xc000013a). and unhandle exception is shown, what do i do ?
2013-04-06 05:21:04 -0600 commented answer error in compliling

i trace the line by line ,when i commnet this line //face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) ); code runs but face and eyes don't detect, when I remove comment ( // ) i get error ( cv::Exception at memory location 0x001ff448.. ) as i explain above

no dear , in real code on my pc ) exist but i get error yet
2013-04-06 03:02:06 -0600 commented answer error in compliling

hi, thanks, i try absolute path but it is issue yet. but i resolve haarcascade_frontalface_alt.xml" . bottleneck that cause the error is face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) ; when i do comment this program run without any error but not work correctly
2013-04-06 02:27:41 -0600 commented question error in compliling

i review again , problem is for these two lines: if( !face_cascade.load( face_cascade_name ) ){ printf("--(!)Error loading\n"); return -1; }; if( !eyes_cascade.load( eyes_cascade_name ) ){ printf("--(!)Error loading\n"); return -1; }; when i do comment these lines program run but not work , two xml file is near project file too

hi, there is no path in opencv 2.4.4 to setting. but there is in 2.3.1

hi, friends I exteract opencv 2.3 and 2.4 on my computer. for initial setting in windows opencv 2.4 has no a critical path but opencv 2.3 contains this: c:\opencv\build\common\tbb\ia32\vc9 and if i use opencv 2.4 my programs encounter error but the same program works with opencv 2.3 is there any alternative addresse that i set for opencv 2.4 or not ? or my opencv 2.4 release is Incomplete.

thank you in advance.

opencv_core231.dll is exist and i do related setting. some other of my program working correctly but 'faceRecognition.exe has error , of course i am beginner to opencv. cheers for advice
