Pattern Learning

This code snippet shows how to learn a pattern defined by a region of interest (ROI).

C++

#include <eVision/EasyMatch/EMatcher.h>

using namespace eVision;
// Image constructor
EImageBW8 srcImage;
// ROI constructor
EROIBW8 pattern;
// EMatcher constructor
EMatcher matcher;
// ...
// Attach the ROI to the source image
// and set its position
pattern.Attach(&srcImage);
pattern.SetPlacement(214, 52, 200, 200);
// Learn the pattern
matcher.LearnPattern(&pattern);

C#

using eVision;

// Image constructor
EImageBW8 srcImage = new EImageBW8();
// ROI constructor
EROIBW8 pattern = new EROIBW8();
// EMatcher constructor
EMatcher matcher = new EMatcher();
// ...
// Attach the ROI to the source image
// and set its position
pattern.Attach(srcImage);
pattern.SetPlacement(214, 52, 200, 200);
// Learn the pattern
matcher.LearnPattern(pattern);
