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. |

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