How to use the analysis API

The following operations need an image converted to a Mat.

Mat img = Imgcodecs.imread("./example.png");

FrameAnalyzer analyzer = new FrameAnalyzer();

analyzer.HSVTargetZoneFinder.setSaturation_value(45);
analyzer.HSVTargetZoneFinder.setHue_value(45);
analyzer.HSVTargetZoneFinder.setValue_value(45);
analyzer.HSVTargetZoneFinder.setMin_area_contour(1000);
/*AND / OR*/
analyzer.HSVTargetZoneFinder.setAutomaticallyCalibratedS(img);

analyzer.targetZoneMaterialsExtractor.setConfidence(90);
analyzer.targetZoneMaterialsExtractor.setLengthOfCut(5);
analyzer.targetZoneMaterialsExtractor.setNumberOfClusters(4);

List<PointOfInterest> poiList = analyzer.getDetailedPOIsFromImage(img);
