Field Details

regionRadius

public double regionRadius

Size of the region's radius. If set to a value ≤ 0, then it will be changed to canonical radius

surf

protected DescribePointSurf<II extends ImageGray<II>> surf

orientation

protected OrientationIntegral<II extends ImageGray<II>> orientation

Constructor Details

DescribeSurf_Point

public DescribeSurf_Point(DescribePointSurf<II> surf,
 OrientationIntegral<II> orientation,
 double regionRadius,
 Class<T> imageType)

Method Details

setImage

public void setImage(T image)

Description copied from interface: DescribePoint

Specified the image which is to be processed.

Specified by:

setImage in interface DescribePoint<T extends ImageGray<T>,II extends ImageGray<II>>

Parameters:

image - The image which contains the features.

process

public boolean process(double x,
 double y,
 TupleDesc_F64 storage)

Description copied from interface: DescribePoint

Extract a description of the local image at the the pixel coordinate of the point. WARNING: Check the returned value to make sure a description was actually computed. Some implementations might now allow features to extend outside the image border and will return false.

Specified by:

process in interface DescribePoint<T extends ImageGray<T>,II extends ImageGray<II>>

Parameters:

x - Coordinate of the point.

y - Coordinate of the point.

storage - (output) Storage for extracted feature. Use DescriptorInfo.createDescription() to create descriptor.

Returns:

true if a descriptor can computed or false if not.

createDescription

public TupleDesc_F64 createDescription()

Description copied from interface: DescriptorInfo

Creates new description instance which can be processed by this class

Specified by:

createDescription in interface DescriptorInfo<T extends ImageGray<T>>

Returns:

New descriptor

getImageType

public ImageType<T> getImageType()

Description copied from interface: DescribePoint

Description of the type of image it can process

Specified by:

getImageType in interface DescribePoint<T extends ImageGray<T>,II extends ImageGray<II>>

Returns:

ImageDataType

getDescriptionType

public Class<TupleDesc_F64> getDescriptionType()

Description copied from interface: DescriptorInfo

The type of region descriptor generated

Specified by:

getDescriptionType in interface DescriptorInfo<T extends ImageGray<T>>

Returns:

Returns the descriptor type.
