Constructor & Destructor Documentation

jafar::fdetect::FloatDescriptor::FloatDescriptor	(	jafar::fdetect::InterestFeature *	ip,
		int	deslength,
		const float *	descr,
		double	normalizeCoef
	)

Parameters:

ip	the interest point associated with this descriptor
deslength	the number of elements in the descriptor
descr	an array with the values of the descriptor
normalizeCoef	normalization coeficient used in strongComparison for the square distance

virtual double jafar::fdetect::FloatDescriptor::strongComparison	(	jafar::fdetect::Descriptor *	snd,
		double	angle
	)		const `[virtual]`

The strong comparison for this descriptor is the square distance.

Parameters:

angle is not used by that kind of descriptor which are invariant by rotation.

Returns:: 1.0 - sum( ( this->m_descr[i] - snd->m_dscr[i] )^2 ) / m_normalizeCoef
