+Structured forests for fast edge detection {#tutorial_ximgproc_prediction}
+==========================================
+
+Introduction
+------------
+
+In this tutorial you will learn how to use structured forests for the purpose of edge detection in
+an image.
+
+Examples

+@note binarization techniques like Canny edge detector are applicable to edges produced by both
+algorithms (Sobel and StructuredEdgeDetection::detectEdges).
