fl::DescriptorCombo Class Reference

#include <descriptor.h>

Inheritance diagram for fl::DescriptorCombo:

List of all members.

Public Methods
	DescriptorCombo ()
	DescriptorCombo (std::istream &stream)
virtual	~DescriptorCombo ()
	Delete all descriptors we are holding.
void	add (Descriptor *descriptor)
	Append another descriptor to the list. This object takes responsibility for the pointer.
virtual Vector< float >	value (const Image &image, const PointAffine &point)
	Returns a vector of floats that describe the image patch near the interest point.
virtual Vector< float >	value (const Image &image)
	Describe entire region that has non-zero alpha values. Descriptor may treat all non-zero alpha values the same, or use them to weight the pixels. This method is only available in Descriptors that don't require a specific point of reference. IE: a spin image must have a central point, so it can't implement this method.
virtual Image	patch (const Vector< float > &value)
	Return a graphical representation of the descriptor. Preferrably an image patch that would stimulate this descriptor to return the given value.
Image	patch (int index, const Vector< float > &value)
	Returns a visualization of one specific feature vector in the set.
virtual Comparison *	comparison ()
	Return an instance of the recommended Comparison for feature vectors from this type of Descriptor. Caller is responsible to destroy instance.
virtual void	read (std::istream &stream)
virtual void	write (std::ostream &stream, bool withName=true)
Public Attributes
std::vector< Descriptor * >	descriptors
void *	lastBuffer
	For detecting change in cached image.
double	lastTime
	For detecting change in cached image.
Image	grayImage

Detailed Description

Applies several descriptors to a patch at once and returns the concatenation of all their feature vectors.

Constructor & Destructor Documentation

DescriptorCombo::DescriptorCombo (    )

DescriptorCombo::DescriptorCombo (  std::istream &    stream )

DescriptorCombo::~DescriptorCombo (    )  [virtual]

Delete all descriptors we are holding.

Member Function Documentation

void DescriptorCombo::add (  Descriptor *    descriptor )

Append another descriptor to the list. This object takes responsibility for the pointer.

Comparison * DescriptorCombo::comparison (    )  [virtual]

Return an instance of the recommended Comparison for feature vectors from this type of Descriptor. Caller is responsible to destroy instance. Reimplemented from fl::Descriptor.

Image DescriptorCombo::patch (  int    index, const Vector< float > &    value )

Returns a visualization of one specific feature vector in the set.

Image DescriptorCombo::patch (  const Vector< float > &    value )  [virtual]

Return a graphical representation of the descriptor. Preferrably an image patch that would stimulate this descriptor to return the given value. Implements fl::Descriptor.

void DescriptorCombo::read (  std::istream &    stream )  [virtual]

Reimplemented from fl::Descriptor.

Vector< float > DescriptorCombo::value (  const Image &    image )  [virtual]

Describe entire region that has non-zero alpha values. Descriptor may treat all non-zero alpha values the same, or use them to weight the pixels. This method is only available in Descriptors that don't require a specific point of reference. IE: a spin image must have a central point, so it can't implement this method. Reimplemented from fl::Descriptor.

Vector< float > DescriptorCombo::value (  const Image &    image, const PointAffine &    point )  [virtual]

Returns a vector of floats that describe the image patch near the interest point. Implements fl::Descriptor.

void DescriptorCombo::write (  std::ostream &    stream, bool    withName = true )  [virtual]

Reimplemented from fl::Descriptor.
