                GaussianBlur(gray_old, gray_old, cv::Size(11, 11), 1.5, 1.5);
             frame = cvQueryFrame(capture);
              cvCopy(frame,frame); //it's important if u make the image in 3 channel or filtering
             pictureBox1->Image  = gcnew    //replacement of cvShowImage
             System::Drawing::Bitmap(frame->width,frame->height,frame->widthStep,
             System::Drawing::Imaging::PixelFormat::Format24bppRgb,(System::IntPtr) frame->imageData);
             pictureBox1->Refresh();
