Canny Edge Detector

This code snippet shows how to highlight edges by means of the Canny edge detector algorithm.

C++

#include <eVision/EasyImage/ECannyEdgeDetector.h>

using namespace eVision;
// Images constructor
EImageBW8 srcImage;
EImageBW8 dstImage;
// ...
// Canny edge detector
ECannyEdgeDetector canny;
// Source and destination images must have the same size
dstImage.SetSize(&srcImage);
// Perform the edges detection
canny.Apply(srcImage, dstImage);

C#

using eVision;

// Images constructor
EImageBW8 srcImage = new EImageBW8();
EImageBW8 dstImage = new EImageBW8();
// ...
// Canny edge detector
ECannyEdgeDetector canny = new ECannyEdgeDetector();
// Source and destination images must have the same size
dstImage.SetSize(srcImage);
// Perform the edges detection
canny.Apply(srcImage, dstImage);
