Detailed Description
template<class VALUETYPE>
class vigra::FindROISize< VALUETYPE >
Calculate the size of an ROI in an image.
This Functor is often used in conjunction with ArrayOfRegionStatistics to find the sizes of all regions in a labeled image.
Traits defined:
FunctorTraits::isUnaryAnalyser and FunctorTraits::isInitializer are true (VigraTrueType)
Usage:
#include <vigra/inspectimage.hxx>
Namespace: vigra
vigra::BImage img, mask;
vigra::FindROISize<vigra::BImage::PixelType> roisize; // init functor
vigra::inspectImageIf(srcImageRange(img), srcImage(mask), roisize);
cout << "Size of ROI: " << roisize.count;
