WrapDescribeBriefSo

public WrapDescribeBriefSo(DescribePointBriefSO<T> alg,
                   java.lang.Class<T> imageType)

Method Detail

createDescription

public TupleDesc_B createDescription()

Description copied from interface: DescriptorInfo

Creates new description instance which can be processed by this class

Specified by:

createDescription in interface DescriptorInfo<TupleDesc_B>

Returns:

New descriptor

setImage

public void setImage(T image)

Description copied from interface: DescribeRegionPoint

Specified the image which is to be processed.

Specified by:

setImage in interface DescribeRegionPoint<T extends boofcv.struct.image.ImageSingleBand,TupleDesc_B>

Parameters:

image - The image which contains the features.

process

public boolean process(double x,
              double y,
              double orientation,
              double scale,
              TupleDesc_B storage)

Description copied from interface: DescribeRegionPoint

Extract a description of the local image at the given point, scale, and orientation. 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 DescribeRegionPoint<T extends boofcv.struct.image.ImageSingleBand,TupleDesc_B>

Parameters:

x - Coordinate of the point.

y - Coordinate of the point.

orientation - Direction the feature is pointing at in radians. 0 = x-axis PI/2 = y-axis

scale - Scale at which the feature was found.

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

Returns:

true if a descriptor can computed or false if not.

requiresScale

public boolean requiresScale()

Description copied from interface: DescribeRegionPoint

If scale information is used when computing the descriptor.

Specified by:

requiresScale in interface DescribeRegionPoint<T extends boofcv.struct.image.ImageSingleBand,TupleDesc_B>

Returns:

if scale needs to be provided or not

requiresOrientation

public boolean requiresOrientation()

Description copied from interface: DescribeRegionPoint

True if the descriptor uses orientation information.

Specified by:

requiresOrientation in interface DescribeRegionPoint<T extends boofcv.struct.image.ImageSingleBand,TupleDesc_B>

Returns:

if orientation needs to be provided or not

getImageType

public boofcv.struct.image.ImageType<T> getImageType()

Description copied from interface: DescribeRegionPoint

Description of the type of image it can process

Specified by:

getImageType in interface DescribeRegionPoint<T extends boofcv.struct.image.ImageSingleBand,TupleDesc_B>

Returns:

ImageDataType

getDescriptionType

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

Description copied from interface: DescriptorInfo

The type of region descriptor generated

Specified by:

getDescriptionType in interface DescriptorInfo<TupleDesc_B>

Returns:

Returns the descriptor type.
