Enhance StreamingStatisticsMapFromLabelImageFilter

Rémi Cresson requested to merge enhance_mapfromlabelstats into develop

Summary

Improves the otbStreamingStatisticsMapFromLabelImageFilter with the following enhancements:

  • Compute count, mean, standard deviation, min, max
  • Multithreaded

Rationale

A class named StatisticsAccumulator handles the update of statistics. I feel that in a near future refactoring we could create such container(s) for statistics. This way, we could reuse this in many otb image statistics components (StreamingImageStatistics and co.). Moreover, we could enrich the persistent filter base classes to enable the (optional) native support of MPI. (But of courses this deserve a complete new RFC)
