Detailed Description

ICL's New Generic Surf Feature detection class.

Internally, the class either uses the opensurf-based implementation or an OpenCL-based implementation based on the clsurf library. The OpenSurf backend needs OpenCV, while the clsurf-backend builds on mandatory OpenCL support.

Constructor & Destructor Documentation

◆ SurfFeatureDetector()

icl::cv::SurfFeatureDetector::SurfFeatureDetector	(	int	octaves = `5`,
		int	intervals = `4`,
		int	sampleStep = `2`,
		float	threshold = `0.00005f`,
		const std::string &	plugin = `"best"`
	)

Constructor with given SURF detection parameters.

plugin can be either "opensurf" or "clsurf" or "best", which will prefer "clsurf" if possible

◆ ~SurfFeatureDetector()

icl::cv::SurfFeatureDetector::~SurfFeatureDetector ( )

Member Function Documentation

◆ detect()

const std::vector<SurfFeature>& icl::cv::SurfFeatureDetector::detect ( const core::ImgBase * image )

detects SURF features in given image

◆ getReferenceFeatures()

const std::vector<SurfFeature>& icl::cv::SurfFeatureDetector::getReferenceFeatures ( ) const

returns the featuers internally stored as reference

◆ match()

const std::vector<SurfMatch>& icl::cv::SurfFeatureDetector::match	(	const core::ImgBase *	image,
		float	significance = `0.65`
	)

detections SURF features and matches them against the given reference features

◆ setIntervals()

void icl::cv::SurfFeatureDetector::setIntervals ( int intervals )

◆ setOctaves()

void icl::cv::SurfFeatureDetector::setOctaves ( int octaves )

◆ setReferenceImage()

void icl::cv::SurfFeatureDetector::setReferenceImage ( const core::ImgBase * image )

detects SURF features in given image and stores them as internal reference features

Please note, that the reference image is internally stored (by deep copy) When parameters are changed and the back-end must be re-initialized, the copy of the reference image is used to compute a new reference feature set based on the new parameters.

◆ setSampleStep()

void icl::cv::SurfFeatureDetector::setSampleStep ( int sampleStep )

◆ setThreshold()

void icl::cv::SurfFeatureDetector::setThreshold ( float threshold )
