Detailed Description

template<class TInputImageType>
class itk::ShortestPathCostFunctionLiveWire< TInputImageType >

Cost function for LiveWire purposes. Specific features are considered to calculate cummulative costs of a link between two pixels. These are:

  • Gradient Magnitude
  • Gradient Direction
  • Laplacian Zero Crossing

By default the Gradient Magnitude is mapped linearly to cost values between 0 (good) and 1 (bad). Via SetDynamicCostMap( std::map< int, int > &costMap) a cost map can be set to dynamically map Gradient Magnitude (non linear). Thus, lower values can be considered with lower costs than higher values of gradient magnitudes. To compute the costs of the gradient magnitude dynamically an iverted map of the histogram of gradient magnitude image is used.
