HI everybody!

i want create Morphological operation Dilation and erosion, i m using Format_Mono for create binary image this is my code:
Qt Code: 
  1. QImage BinaryImage::createProbe(int width, int height, bool *data[])
  2. {
  3.     QImage temp(width,height,QImage::Format_Mono);
  4.     for(int i=0; i<width;i++)
  5.         for(int j=0; j<height;j++)
  6.             temp.setPixel(i,j,(uint) data[i][j]);
  7.  
  8.     return temp;
  9. }
  10.  
  11. bool **data;
  12.     data = new bool*[3];
  13.     for(int i=0;i<3;i++)
  14.        data[i] = new bool[3];
  15.  
  16.     for(int i=0;i<3;i++)
  17.         for(int j=0;j<3;j++)
  18.             data[i][j] = 1;
  19.  
  20. BinaryImage::createProbe(3,3,data);
To copy to clipboard, switch view to plain text mode 

this work great, i convert a Rgb32 image to Binary image with this code:
Qt Code: 
  1. void BinaryImage::convertToBinary(QImage* image,float treshholding)
  2. {
  3.     QImage temp(image->width(),image->height(),QImage::Format_Mono);
  4.  
  5.     if(image->isNull()) return;
  6.  
  7.     for(int i=0; i < image->height();i++)
  8.     {
  9.         QRgb* p =(QRgb *)image->scanLine(i);
  10.         for(int j=0;j<image->width();j++)
  11.         {
  12.           int c = (qRed(p[j])+qGreen(p[j])+qBlue(p[j]))/3;
  13.           c = (c > treshholding * 1000)? 1 : 0;
  14.           temp.setPixel(j,i,c);
  15.       }
  16.     }
  17.  
  18.     *image = temp;
  19. }
To copy to clipboard, switch view to plain text mode 

this works great too.

but my function for create dilation image is like this:
Qt Code: 
  1. Morphology::Morphology(QImage image, QImage probe)
  2. {
  3.     if(image.format() == QImage::Format_Mono || probe.format() == QImage::Format_Mono)
  4.     {
  5.        this->image = image;
  6.        this->probe = probe;
  7.     }
  8. }
  9.  
  10. QImage Morphology::applyDilation()
  11. {
  12.     QImage dest(image.width(),image.height(),QImage::Format_Mono);
  13.  
  14.     QVector<uchar> pix_values;
  15.     int i,j;
  16.  
  17.     for(int row =0;row<image.height();row++)
  18.     {
  19.         //uchar* dst_row_ptr = dest.scanLine(row);
  20.         for(int column = 0; column < image.width(); column++)
  21.         {
  22.             pix_values.clear();
  23.             for(int prow = 0; prow < probe.height(); prow++)
  24.             {
  25.                 i = prow + row - probe.height() / 2;
  26.                 //uchar* img_row_ptr = image.scanLine(i);
  27.                 //uchar* prb_row_ptr = probe.scanLine(prow);
  28.  
  29.                 for(int pcolumn = 0; pcolumn < probe.width(); pcolumn++)
  30.                 {
  31.                     j = column + pcolumn - probe.width() / 2;
  32.                     if(i >= 0 && i < image.height() && j >= 0 && j < image.width())
  33.                         if(probe.pixelIndex(prow, pcolumn) == 1)
  34.                             pix_values.push_back(image.pixelIndex(i, j));
  35.                 }
  36.             }
  37.             dest.setPixel(row,column,(uint)*std::max_element(pix_values.begin(), pix_values.end())); //the max goes in the destination
  38.         }
  39.     }
  40.  
  41.     return dest;
  42. }
  43.  
  44. //run code is this
  45. BinaryImage::convertToBinary(img,0.17);
  46.  
  47.     bool **data;
  48.     data = new bool*[3];
  49.     for(int i=0;i<3;i++)
  50.        data[i] = new bool[3];
  51.  
  52.     for(int i=0;i<3;i++)
  53.         for(int j=0;j<3;j++)
  54.             data[i][j] = 1;
  55.     Morphology morph(*img,BinaryImage::createProbe(3,3,data));
  56.     imageLabel->setPixmap(QPixmap::fromImage(morph.applyDilation()));
  57.     imageLabel->adjustSize();

this function is work too but get a lot of warnings QImage:ixelInde() that is out of range and run program too slow.
what is the problem?
what i can do for i havent any warning and run program fast?
