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()

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()
