+
+This subsection focuses not on the big picture but compares vanilla SSD
+with Bayesian SSD with respect to specific images that illustrate
+similarities and differences between both approaches. For this
+comparison, 0.2 confidence threshold is applied. Furthermore, Bayesian
+SSD uses non-maximum suppression and dropout with 0.9 keep ratio.

+\end{figure}
+
+In the ground truth, only a stop sign and a truck are detected in figure \ref{fig:stop-sign-truck}. The truck is neither detected by vanilla nor Bayesian SSD. Instead both detected a pottet plant and a traffic light.
+The stop sign is detected by both variants.
