Create an array of dynamic accumulator chains containing the selected per-region and global statistics and their dependencies.
DynamicAccumulatorChainArray is used to compute per-region statistics (as well as global statistics) with run-time activation. A set of statistics is selected at run-time and from this set statistics can be activated at run-time by calling activate<stat>() or activate(std::string stat).
The template parameters are as follows:
Usage:
const int dim = 3; //dimension of MultiArray typedef double DataType; typedef double WeightType; typedef unsigned int LabelType; typedef vigra::CoupledIteratorType<dim, DataType, WeightType, LabelType>::HandleType Handle; DynamicAccumulatorChainArray<Handle, Select<DataArg<1>, WeightArg<2>, LabelArg<3>, Mean, Variance, ...> > a;
See Feature Accumulators for more information and examples of use.
void activate | ( | std::string | tag | ) |
Activate statistic 'tag'. Alias names are not recognized. If the statistic is not in the accumulator chain a PreconditionViolation is thrown.
void activate | ( | ) |
activate<TAG>() activates statistic 'TAG'. If the statistic is not in the accumulator chain it is ignored. (?)
void activateAll | ( | ) |
Activate all statistics in the accumulator chain.
bool isActive | ( | std::string | tag | ) | const |
Return true if the statistic 'tag' is active, i.e. activate(std::string tag) or activate<TAG>() has been called. If the statistic is not in the accumulator chain a PreconditionViolation is thrown. (Note that alias names are not recognized.)
bool isActive | ( | ) | const |
isActive<TAG>() returns true if statistic 'TAG' is active, i.e. activate(std::string tag) or activate<TAG>() has been called. If the statistic is not in the accumulator chain, true is returned. (?)
ArrayVector<std::string> activeNames | ( | ) | const |
Return names of all statistics in the accumulator chain that are active.
unsigned int passesRequired | ( | ) | const |
Return number of passes required to compute the active statistics in the accumulator chain.
