Constructor & Destructor Documentation

TwoStepLocalLengthEstimator() [1/3]

template<typename TConstIterator>

DGtal::TwoStepLocalLengthEstimator< TConstIterator >::TwoStepLocalLengthEstimator ( )

delete

Default Constructor.

TwoStepLocalLengthEstimator() [2/3]

template<typename TConstIterator>

DGtal::TwoStepLocalLengthEstimator< TConstIterator >::TwoStepLocalLengthEstimator	(	const double	wdirect,
		const double	wdiag )

Constructor with direct and diagonal weights.

Parameters

wdirect	direct weight
wdiag	diagonal weight

~TwoStepLocalLengthEstimator()

template<typename TConstIterator>

DGtal::TwoStepLocalLengthEstimator< TConstIterator >::~TwoStepLocalLengthEstimator ( )

default

Destructor.

TwoStepLocalLengthEstimator() [3/3]

template<typename TConstIterator>

DGtal::TwoStepLocalLengthEstimator< TConstIterator >::TwoStepLocalLengthEstimator ( const TwoStepLocalLengthEstimator< TConstIterator > & other )

delete

Copy constructor.

Parameters

other

the object to clone. Forbidden by default.

Member Function Documentation

eval()

template<typename TConstIterator>

Quantity DGtal::TwoStepLocalLengthEstimator< TConstIterator >::eval	(	const ConstIterator &	itb,
		const ConstIterator &	ite,
		const double	h = 1. ) const

Computation of the l1 length of the curve. Iterated structure must contain pairs. The direct or diagonal case is resolved using the dot function on the second element of pairs. Complexity: O(|Range|)

Parameters

itb	begin iterator
ite	end iterator
h	grid size (must be > 0).

Returns

the curve length.

isValid()

template<typename TConstIterator>

bool DGtal::TwoStepLocalLengthEstimator< TConstIterator >::isValid

(

)

const

Checks the validity/consistency of the object.

Returns

'true' if the object is valid, 'false' otherwise.

Referenced by DGtal::BLUELocalLengthEstimator< TConstIterator >::selfDisplay(), and DGtal::RosenProffittLocalLengthEstimator< TConstIterator >::selfDisplay().

operator=()

template<typename TConstIterator>

TwoStepLocalLengthEstimator & DGtal::TwoStepLocalLengthEstimator< TConstIterator >::operator= ( const TwoStepLocalLengthEstimator< TConstIterator > & other )

delete

Assignment.

Parameters

other

the object to copy.

Returns

a reference on 'this'. Forbidden by default.

selfDisplay()

template<typename TConstIterator>

void DGtal::TwoStepLocalLengthEstimator< TConstIterator >::selfDisplay

(

std::ostream &

out

)

const

Writes/Displays the object on an output stream.

Parameters

out	the output stream where the object is written.
