Constructor Detail

InterestPointDetectorOverride

public InterestPointDetectorOverride(InterestPointDetector<T> detector,
                                     OrientationImage<T> orientation)

Specifies which algorithms are to be used. If orientation is specified then it will override the orientation provided by 'detector'

Parameters:

detector - Interest point detector and default scale and orientation.

orientation - If not null then this will be used to estimate the feature's orientation.

Method Detail

detect

public void detect(T input)

Description copied from interface: InterestPointDetector

Detects interest points inside the provided image.

Specified by:

detect in interface InterestPointDetector<T extends boofcv.struct.image.ImageGray>

Parameters:

input - Input features are detected inside of.

getNumberOfFeatures

public int getNumberOfFeatures()

Description copied from interface: FoundPointSO

Returns the number of interest points found.

Specified by:

getNumberOfFeatures in interface FoundPointSO

Returns:

Number of interest points.

getLocation

public georegression.struct.point.Point2D_F64 getLocation(int featureIndex)

Description copied from interface: FoundPointSO

The center location of the feature inside the image.

WARNING: Do not save the returned reference, copy instead. The returned point can be recycled each time this function is called.

Specified by:

getLocation in interface FoundPointSO

Parameters:

featureIndex - The feature's index.

Orientation in radians.

hasScale

public boolean hasScale()

Description copied from interface: InterestPointDetector

Does the interest point detector have scale information

Specified by:

hasScale in interface InterestPointDetector<T extends boofcv.struct.image.ImageGray>

Returns:

true if it has scale information and false otherwise

hasOrientation

public boolean hasOrientation()

Description copied from interface: InterestPointDetector

If the interest point detector estimates the feature's orientation

Specified by:

hasOrientation in interface InterestPointDetector<T extends boofcv.struct.image.ImageGray>
