IntensityExtrema

Computes basic minimum and maximum intensities of an image.

Access to parameter description

For an introduction: For an image I This algorithm supports grayscale, color, multi-channel images, 3D volumes, and time series as inputs. The policy to manage the dimensions in each case can be defined with the splitResult parameter.

IntensityExtrema intensityExtremaAlgo;
intensityExtremaAlgo.setInputImage( polystyrene );
intensityExtremaAlgo.setSplitResult( 0 );
intensityExtremaAlgo.execute();

std::cout << "maximum: " << intensityExtremaAlgo.outputMeasurement()->maximum( 0 , 0 , 0 ) ;

Function Examples

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