OpenCV удаляет краевые пятна?

Question

Я пытаюсь использовать следующий код для удаления пятен, пятен на краю верхнего правого угла, не смог его удалить, что мне делать?

CvContourScanner scanner = NULL; сканер = cvStartFindContours (img_src, storage, sizeof (CvContour), CV_RETR_CCOMP, CV_CHAIN_APPROX_NONE, cvPoint (0,0));

CvRect rect; 
while (contour=cvFindNextContour(scanner)) 
{ 
    tmparea = fabs(cvContourArea(contour)); 
    rect = cvBoundingRect(contour,0); 
    if (tmparea < minarea/*||tmparea>4900*/) 
    { 

     pp=(uchar*)(img_Clone->imageData + img_Clone->widthStep*(rect.y+rect.height/2)+rect.x+rect.width/2); 
     if (pp[0]==0) 
     { 
      for(int y = rect.y;y<rect.y+rect.height;y++) 
      { 
       for(int x =rect.x;x<rect.x+rect.width;x++) 
       { 
        pp=(uchar*)(img_Clone->imageData + img_Clone->widthStep*y+x); 

        if (pp[0]==0) 
        { 
         pp[0]=255; 
        } 
       } 
      } 
     } 

    } 
}
