otbStreamingStatisticsMapFromLabelImageFilter with the following enhancements:
- Compute count, mean, standard deviation, min, max
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)
