+    - demonstrates parameter prediction networks for line drawings using extended difference of gaussians(xDoG), trained on the APdrawing dataset
+    - The effect pipeline uses a post-processing cnn, to stylize features which are not able to be stylized by xDoG. 
+    - To see the xdog output without post-processing, click the checkmark. Control the global parameters of xDoG using the sliders
