Detailed Description

template<typename TIterator, typename TInteger = typename IteratorCirculatorTraits<TIterator>::Value::Coordinate, unsigned short adjacency = 8>
class DGtal::ArithmeticalDSSComputer< TIterator, TInteger, adjacency >

Aim: This class is a wrapper around ArithmeticalDSS that is devoted to the dynamic recognition of digital straight segments (DSS) along any sequence of digital points.

See Digital straight lines and segments
for further details. See also classes NaiveDSS8Computer and StandardDSS4Computer, which are aliases of this class.

Template Parameters
TIteratortype of iterator on 2d digital points, at least readable and forward.
TIntegertype of integers used for the computation of remainders, which is a model of CInteger.
adjacencyan unsigned integer equal to 4 for standard (simply 4-connected) DSS or 8 for naive (simply 8-connected) DSS (default).

This class is a model of CDynamicBidirectionalSegmentComputer. It is also default constructible, copy constructible, assignable and equality comparable.
