Method Detail

createDescription

public BrightFeature createDescription()

Description copied from interface: DescriptorInfo

Creates new description instance which can be processed by this class

Specified by:

createDescription in interface DescriptorInfo<BrightFeature>

Returns:

New descriptor

getDescription

public BrightFeature getDescription(int index)

Description copied from interface: DetectDescribePoint

Returns the feature descriptor at the specified index.

WARNING: The returned data structure is recycled each time InterestPointDetector.detect(boofcv.struct.image.ImageBase) is called. Create a copy if this is a problem.

Specified by:

getDescription in interface DetectDescribePoint<In extends ImageGray,BrightFeature>

Parameters:

index - Which feature

Returns:

Feature descriptor

getDescriptionType

public java.lang.Class<BrightFeature> getDescriptionType()

Description copied from interface: DescriptorInfo

The type of region descriptor generated

Specified by:

getDescriptionType in interface DescriptorInfo<BrightFeature>

Returns:

Returns the descriptor type.

detect

public void detect(In input)

Description copied from interface: InterestPointDetector

Detects interest points inside the provided image.

Specified by:

detect in interface InterestPointDetector<In extends ImageGray>

Specified by:

getNumberOfFeatures in interface FoundPointSO

Returns:

Number of interest points.

getLocation

public 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.
