detectMultiScale3() [1/7]

void OpenCVForUnity.ObjdetectModule.CascadeClassifier.detectMultiScale3	(	Mat	image,
		MatOfRect	objects,
		MatOfInt	rejectLevels,
		MatOfDouble	levelWeights,
		double	scaleFactor,
		int	minNeighbors,
		int	flags,
		Size	minSize,
		Size	maxSize,
		bool	outputRejectLevels
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. This function allows you to retrieve the final stage decision certainty of classification. For this, one needs to set outputRejectLevels on true and provide the rejectLevels and levelWeights parameter. For each resulting detection, levelWeights will then contain the certainty of classification at the final stage. This value can then be used to separate strong from weaker classifications.

A code sample on how to use it efficiently can be found below:

Mat img;
vector<double> weights;
vector<int> levels;
vector<Rect> detections;
CascadeClassifier model("/path/to/your/model.xml");
model.detectMultiScale(img, detections, levels, weights, 1.1, 3, 0, Size(), Size(), true);
cerr << "Detection " << detections[0] << " with weight " << weights[0] << endl;
