Constructor Detail

GenericDenseDescribeImageDense

public GenericDenseDescribeImageDense(DescribeRegionPoint<T,Desc> alg,
                                      double scaleToRadius)

Configures dense description.

Parameters:

alg - Sparse feature sampler.

Method Detail

configure

public void configure(double scale,
                      double periodX,
                      double periodY)

Description copied from interface: DescribeImageDense

Configures how features are sampled across the image.

NOTE: The specific implementation is allowed to tweak these numbers. The period might be adjusted to ensure an even sampling across the entire image is done.

Specified by:

configure in interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>

Parameters:

scale - Scales the size of the region the descriptor is computed up or down, e.g. 2 = twice as large. Try 1.0

periodX - Pixels between samples along x-axis

periodY - Pixels between samples along y-axis

process

public void process(T input)

Description copied from interface: DescribeImageDense

Processes the image and computes the dense image features.

Specified by:

process in interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>

Parameters:

input - Input image.

getDescriptions

public java.util.List<Desc> getDescriptions()

Description copied from interface: DescribeImageDense

Returns a list of the computed descriptions.

The list and everything contained inside of it are owned by this class and subject to modification the next time DescribeImageDense.process(ImageBase) is called.

Specified by:

getDescriptions in interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>

Returns:

list of descriptions

getLocations

public java.util.List<georegression.struct.point.Point2D_I32> getLocations()

Description copied from interface: DescribeImageDense

Returns a list of locations that the descriptors are computed at

The list and everything contained inside of it are owned by this class and subject to modification the next time DescribeImageDense.process(ImageBase) is called.

Specified by:

getLocations in interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>

Returns:

list of descriptions

getImageType

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

Description copied from interface: DescribeImageDense

Description of the type of image it can process

Specified by:

getImageType in interface DescribeImageDense<T extends boofcv.struct.image.ImageBase,Desc extends TupleDesc>

Returns:

ImageDataType

createDescription

public Desc createDescription()

Description copied from interface: DescriptorInfo

Creates new description instance which can be processed by this class

Specified by:

createDescription in interface DescriptorInfo<Desc extends TupleDesc>

Returns:

New descriptor

getDescriptionType

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

Description copied from interface: DescriptorInfo

The type of region descriptor generated

Specified by:

getDescriptionType in interface DescriptorInfo<Desc extends TupleDesc>

Returns:

Returns the descriptor type.
