Hi, I would like to put the output in the white area, this is my GUIhaar.JPG,and this output擷取.JPG
This is my code:
Qt Code: 
  1. #include "haar.h"
  2. #include "ui_haar.h"
  3. #include "opencv2/objdetect/objdetect.hpp"
  4. #include "opencv2/highgui/highgui.hpp"
  5. #include "opencv2/imgproc/imgproc.hpp"
  6. #include <iostream>
  7. using namespace std;
  8. using namespace cv;
  9. HAAR::HAAR(QWidget *parent) :
  10.     QMainWindow(parent),
  11.     ui(new Ui::HAAR)
  12. {
  13.     ui->setupUi(this);
  14. }
  15.  
  16. HAAR::~HAAR()
  17. {
  18.     delete ui;
  19. }
  20.  
  21. void HAAR::on_pushButton_clicked()
  22. {
  23.     Mat frame;
  24.         //VideoCapture cap(0);
  25.             //while(true){
  26.             //cap>>frame;
  27.  
  28.         frame=cv::imread("C:\\Users\\OpenCL\\Documents\\QT Pro\\H\\1.jpg");//read image.
  29.         //double t = (double)getTickCount();
  30.         float A[30][30];
  31.         //float **A = (float**)malloc(sizeof(float)*(frame.cols+1)*(frame.rows+1));
  32.         //for(int k=0;k<frame.cols+1;k++)	A[k]=(float*)malloc(sizeof(float)*(frame.rows+1));
  33.         for(int i=0;i<frame.cols+1;i++) for(int j=0;j<frame.rows+1;j++)A[i][j]=0;
  34.             for(int y=0;y<frame.rows;y++){
  35.             float sum=0;
  36.             uchar* ptr1=frame.ptr<uchar>(y);
  37.             for (int x=0; x<frame.cols; x++) {
  38.                 sum=sum+(float)((ptr1[3*x]+ptr1[3*x+1]+ptr1[3*x+2])/3);
  39.  
  40.                 A[x+1][y+1] = A[x+1][y] + sum;
  41.  
  42.             }
  43.             cout<<endl;
  44.         }
  45.  
  46.         cout<<"Integration Picture:"<<endl<<endl;
  47.             for(int j=0;j<frame.rows+1;j++,cout<<endl)
  48.                 for(int i=0 ;i<frame.cols+1;i++)
  49.                 {
  50.                   cout<<A[i][j]<<" ";
  51.  
  52.  
  53.             cout<<endl;
  54. }
