Detailed Description

template<class TInputVectorImage, class TLabelImage>
class otb::StreamingStatisticsMapFromLabelImageFilter< TInputVectorImage, TLabelImage >

Computes mean radiometric value for each label of a label image, based on a support VectorImage.

Currently the class only computes the mean value.

This class streams the whole input image through the PersistentStreamingStatisticsMapFromLabelImageFilter.

This way, it allows computing the first order global statistics of this image. It calls the Reset() method of the PersistentStatisticsImageFilter before streaming the image and the Synthetize() method of the PersistentStatisticsImageFilter after having streamed the image to compute the statistics. The accessor on the results are wrapping the accessors of the internal PersistentStatisticsImageFilter.

This filter can be used as:

typedef otb::StreamingStatisticsMapFromLabelImageFilter<ImageType> StatisticsType;
StatisticsType::Pointer statistics = StatisticsType::New();
statistics->SetInput(reader->GetOutput());
statistics->Update();
StatisticsType::PixelValueMapType meanValueMap = statistics->GetMeanValueMap();
StatisticsType::PixelValueMapType::const_iterator end = meanValueMap();
for (StatisticsType::PixelValueMapType::const_iterator it = meanValueMap.begin(); it != end; ++it)
{
      std::cout << "label : " << it->first << " , ";
                << "mean value : " << it->second << std::endl;
}
