示例1: if

   QGraphicsScene * arrangement = new QGraphicsScene();

   QTime time;
   time.start();

   // determine background
   Segment * background = determineBackground(segments);
   SegmentList segmentsWOBack = removeBackground(segments, background);
   arrangement->setBackgroundBrush(QBrush(QColor(background->color().toQRgb())));
   segmentsWOBack.calculateFeatureVariances();

   // initialize layout
   //initializeLayout(segmentsWOBack, segmentsWOBack.featX(), segmentsWOBack.featY());
   initializeLayout(segmentsWOBack, xAxisBox->currentIndex(), yAxisBox->currentIndex());

   // find clusters
   time.restart();
   QList<SegmentList> clusters = meanShift(segmentsWOBack);
   qDebug("Segments clustered in %f seconds", time.restart()/1000.0);
   qDebug("  %d clusters found", clusters.size());

   // refine clusters
   //int counter = 0;
   foreach (SegmentList cluster, clusters) {
      if (clusterBox->currentIndex() == 0) {
