Image Segmenter

This code snippet shows how to build blobs according to a user-defined image segmenter.

C++

#include <eVision/EasyObject/EasyObject2/EImageEncoder.h>

using namespace eVision;
// Image constructor
EImageBW8 srcImage;
// Image encoder
EImageEncoder encoder;
// Coded image
ECodedImage2 codedImage;
// ...
// Set the segmentation method to GrayscaleDoubleThreshold
encoder.SetSegmentationMethod(ESegmentationMethod_GrayscaleDoubleThreshold);
// Retrieve the segmenter object
Segmenters::EGrayscaleDoubleThresholdSegmenter& segmenter = encoder.GetGrayscaleDoubleThresholdSegmenter();
// Set the high and low threshold values
segmenter.SetHighThreshold(150);
segmenter.SetLowThreshold(50);
// Specify the layers to be encoded (neutral layer only)
segmenter.SetBlackLayerEncoded(false);
segmenter.SetNeutralLayerEncoded(true);
segmenter.SetWhiteLayerEncoded(false);
// Encode the image
encoder.Encode(srcImage, codedImage);
