Member Function Documentation

◆ eval()

template<typename TConstIterator>

Quantity DGtal::TwoStepLocalLengthEstimator< TConstIterator >::eval ( ) const

Computation of the l1 length of the curve. Complexity: O(|Range|)

Precondition: init() method must be called before.

Returns: the curve length.

◆ init()

template<typename TConstIterator>

void DGtal::TwoStepLocalLengthEstimator< TConstIterator >::init	(	const double	h,
		const ConstIterator &	itb,
		const ConstIterator &	ite,
		const bool &	isClosed
	)

Initialize the measure computation.

Parameters

h	grid size (must be >0).
itb	begin iterator
ite	end iterator
isClosed	true if the input range is closed.

◆ 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.

◆ operator=()

template<typename TConstIterator>

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