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:
	cv.AgastFeatureDetector.create(	[, threshold[, nonmaxSuppression[, type]]]	) ->	retval
	cv.AgastFeatureDetector_create(	[, threshold[, nonmaxSuppression[, type]]]	) ->	retval

getDefaultName()

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

virtual

Python:
	cv.AgastFeatureDetector.getDefaultName(		) ->	retval

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:
	cv.AgastFeatureDetector.getNonmaxSuppression(		) ->	retval

getThreshold()

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

pure virtual

Python:
	cv.AgastFeatureDetector.getThreshold(		) ->	retval

getType()

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

pure virtual

Python:
	cv.AgastFeatureDetector.getType(		) ->	retval

setNonmaxSuppression()

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

pure virtual

Python:
	cv.AgastFeatureDetector.setNonmaxSuppression(	f	) ->	None

setThreshold()

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

pure virtual

Python:
	cv.AgastFeatureDetector.setThreshold(	threshold	) ->	None

setType()

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