Constructor & Destructor Documentation

PointSetColorEstimator::PointSetColorEstimator (  ArakMarkovChain &  chain, const Arak::Util::PropertyMap &  props )

Constructor for a grid of point color estimators. This constructor uses the properties "arak.mcmc.estimation.avg_grid.rows" and "arak.mcmc.estimation.avg_grid.cols" to define a grid of points at which the color is estimated. Parameters: chain  the Markov chain generating the samples used for estimation props  a properties map Definition at line 7 of file estimation.cpp. References Arak::QueryPointIndex::addListeners(), Arak::ArakMarkovChain, Arak::MarkovChain< MarkovChainTraits >::getState(), Arak::Util::PropertyMap, and Arak::Geometry::Rectangle.

virtual Arak::PointSetColorEstimator::~PointSetColorEstimator (   )  [inline, virtual]

Destructor. Definition at line 196 of file estimation.hpp. References estimators.

Member Function Documentation

virtual PointColorEstimator* Arak::PointSetColorEstimator::create (  const QueryPoint &  p  )  [inline, virtual]

Creates a new listener for the supplied point. Implements Arak::QueryPointListenerFactory. Definition at line 209 of file estimation.hpp. References Arak::QueryPoint::color(), and estimators.

void PointSetColorEstimator::visualize (  CGAL::Qt_widget &  widget  )  const [virtual]

Renders a graphical representation of this point set color estimator using the supplied widget. The point color estimates are rendered as squares of varying gray level. Todo: Use a Qt image rendering method Parameters: widget  the widget on which to visualize the estimates Definition at line 26 of file estimation.cpp. References Arak::PointColorEstimator::estimate(), estimators, and Arak::PointColorEstimator::point. Referenced by Arak::operator<<().

template<typename charT, typename traits> void Arak::PointSetColorEstimator::write (  std::basic_ostream< charT, traits > &  out  )  const [inline]

Writes an ASCII representation of the current estimates to the supplied stream. Each line is "x y p" where (x, y) is the coordinate of the point and p is the probability the point is black. Parameters: out  the stream on which to write the estimates Definition at line 236 of file estimation.hpp. References Arak::PointColorEstimator::estimate(), estimators, Arak::MarkovChain< MarkovChainTraits >::getNumSamples(), Arak::PointColorEstimator::point, and POINT_SET_ESTIMATE_HEADER.
