Inheritance diagram for fl::DescriptorScale:

fl::Descriptor List of all members.

Public Methods

 DescriptorScale (float firstScale=1, float lastScale=25, int interQuanta=40, float quantum=2)
 quantum is most meaningful as a prime number; 2 means "doubling" or "octaves"

 DescriptorScale (std::istream &stream)
void initialize (float firstScale, float lastScale, float stepSize)
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 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.

virtual void read (std::istream &stream)
virtual void write (std::ostream &stream, bool withName=true)

Public Attributes

std::vector< Laplacian > laplacians
