Definiens Developer 7 - Reference Book3 Algorithms ReferenceSearch RangeDefine the search range in pixels. All image objects with a distance below the givensearch range will be part of the search domain. Use the drop down arrows to select zeroor positive numbers.ConnectedEnable to ensure that all image objects in the search domain are connected with theanalyzed image object via other objects in the search range.Compatibility ModeSelect Yes from the Value field to enable compatibility with older software versions(version 3.5 and 4.0). This parameter will be removed with future versions.ConditionsDefine the extrema conditions.Extrema TypeChoose Minimum for classifying image objects with the smallest feature values andMaximum for classifying image objects with largest feature values.FeatureChoose the feature to use for finding the extreme values.Extrema ConditionThis parameter defines the behaviour of the algorithm if more than one image object isfulfilling the extrema condition.ValueDo not accept equal extremaAccept equal extremaAccept first equal extremaDescriptionNone of the image objects will be classified.All of the image objects will be classified.The first of the image objects will be classified.Classification SettingsSpecifies the classification that will be applied to all image objects fulfilling the extremalcondition.See classification algorithm for details. Classification on page 28NoteAt least one class needs to be selected in the active class list for this algorithm.32
