Member Function Documentation

create()

static Ptr<AgastFeatureDetector> cv::AgastFeatureDetector::create ( int  threshold = 10, bool  nonmaxSuppression = true, AgastFeatureDetector::DetectorType  type = AgastFeatureDetector::OAST_9_16  )

static

Python:
	retval	=	cv.AgastFeatureDetector_create(	[, threshold[, nonmaxSuppression[, type]]]	)

getDefaultName()

virtual String cv::AgastFeatureDetector::getDefaultName ( ) const

virtual

Python:
	retval	=	cv.AgastFeatureDetector.getDefaultName(		)

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

Reimplemented from cv::Feature2D.

getNonmaxSuppression()

virtual bool cv::AgastFeatureDetector::getNonmaxSuppression ( ) const

pure virtual

Python:
	retval	=	cv.AgastFeatureDetector.getNonmaxSuppression(		)

getThreshold()

virtual int cv::AgastFeatureDetector::getThreshold ( ) const

pure virtual

Python:
	retval	=	cv.AgastFeatureDetector.getThreshold(		)

getType()

virtual AgastFeatureDetector::DetectorType cv::AgastFeatureDetector::getType ( ) const

pure virtual

Python:
	retval	=	cv.AgastFeatureDetector.getType(		)

setNonmaxSuppression()

virtual void cv::AgastFeatureDetector::setNonmaxSuppression ( bool  f )

pure virtual

Python:
	None	=	cv.AgastFeatureDetector.setNonmaxSuppression(	f	)

setThreshold()

virtual void cv::AgastFeatureDetector::setThreshold ( int  threshold )

pure virtual

Python:
	None	=	cv.AgastFeatureDetector.setThreshold(	threshold	)

setType()

virtual void cv::AgastFeatureDetector::setType ( AgastFeatureDetector::DetectorType  type )

pure virtual

Python:
	None	=	cv.AgastFeatureDetector.setType(	type	)
