Detailed Description

an adaptively adjusting detector that iteratively detects until the desired number of features are detected. Beware that this is not thread safe - as the adjustment of parameters breaks the const of the detection routine... /TODO Make this const correct and thread safe

sample usage: will create a detector that attempts to find 100 - 110 FAST Keypoints, and will at most run FAST feature detection 10 times until that number of keypoints are found Ptr<FeatureDetector> detector(new DynamicAdaptedFeatureDetector(new FastAdjuster(20,true),100, 110, 10));

Constructor & Destructor Documentation

§ DynamicAdaptedFeatureDetector()

cv::DynamicAdaptedFeatureDetector::DynamicAdaptedFeatureDetector	(	const Ptr< AdjusterAdapter > &	adjuster,
		int	min_features = `400`,
		int	max_features = `500`,
		int	max_iters = `5`
	)

Parameters

adjuster	an AdjusterAdapter that will do the detection and parameter adjustment
max_features	the maximum desired number of features
max_iters	the maximum number of times to try to adjust the feature detector params for the FastAdjuster this can be high, but with Star or Surf this can get time consuming
min_features	the minimum desired features
