Constructors

FastFeatureDetector(int, bool, DetectorType)

Create a fast detector with the specific parameters

public FastFeatureDetector(int threshold = 10, bool nonmaxSupression = true, FastFeatureDetector.DetectorType type = DetectorType.Type9_16)

Parameters

threshold int: Threshold on difference between intensity of center pixel and pixels on circle around this pixel.
nonmaxSupression bool: Specify if non-maximum suppression should be used.
type FastFeatureDetector.DetectorType: One of the three neighborhoods as defined in the paper

Methods

DisposeObject()

Release the unmanaged memory associated with this detector.
