IntensityMaskedStatistics

Computes basic statistics on a region of interest of an image, defined by a binary mask.

Access to parameter description

For an introduction: This algorithm gives the same results as IntensityStatistics taking into account only pixels under a binary mask image.

Object Examples

std::shared_ptr< iolink::ImageView > polystyrene = ioformat::readImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "polystyrene.tif" );
auto polystyrene_mask = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "polystyrene_mask.vip" );

IntensityMaskedStatistics intensityMaskedStatisticsAlgo;
intensityMaskedStatisticsAlgo.setInputImage( polystyrene );
intensityMaskedStatisticsAlgo.setInputMaskImage( polystyrene_mask );
intensityMaskedStatisticsAlgo.execute();

std::cout << "pixelCount: " << intensityMaskedStatisticsAlgo.outputMeasurement()->pixelCount( 0 , 0 ) ;

Function Examples

auto polystyrene_mask = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "polystyrene_mask.vip" );

auto result = intensityMaskedStatistics( polystyrene, polystyrene_mask );

std::cout << "pixelCount: " << result->pixelCount( 0 , 0 ) ;
