GenericDenseDescribeImageDense

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

Configures dense description.

Parameters:

alg - Sparse feature sampler.

scaleToRadius - Conversion between requested descriptor scale to its actual radius

descriptorScale - Relative scale of the descriptor's region

samplePeriodX - How frequently the image is sampled in pixels. X-axis

samplePeriodY - How frequently the image is sampled in pixels. Y-axis

Method Detail

configure

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

Configures size of the descriptor and the frequency at which it's computed

Parameters:

descriptorRegionScale - Relative size of the descriptor region to its canonical size

periodX - Period in pixels along x-axis of samples

periodY - Period in pixels along y-axis of samples

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 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 ImageBase,Desc extends TupleDesc>

Returns:

list of descriptions

getLocations

public java.util.List<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 ImageBase,Desc extends TupleDesc>

Returns:

list of descriptions

getImageType

public ImageType<T> getImageType()

Description copied from interface: DescribeImageDense

getImageType in interface DescribeImageDense<T extends 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
