Beschreibung

compare_variation_modelcompare_variation_modelCompareVariationModelcompare_variation_modelCompareVariationModelCompareVariationModel vergleicht das Eingabebild ImageImageImageImageImageimage mit dem Variationsmodell ModelIDModelIDModelIDModelIDModelIDmodelID. Bevor compare_variation_modelcompare_variation_modelCompareVariationModelcompare_variation_modelCompareVariationModelCompareVariationModel aufgerufen werden kann, müssen mit prepare_variation_modelprepare_variation_modelPrepareVariationModelprepare_variation_modelPrepareVariationModelPrepareVariationModel oder prepare_direct_variation_modelprepare_direct_variation_modelPrepareDirectVariationModelprepare_direct_variation_modelPrepareDirectVariationModelPrepareDirectVariationModel die beiden internen Schwellwertbilder erzeugt worden sein. Sei das aktuelle Bild ImageImageImageImageImageimage durch c(x,y) bezeichnet und die beiden internen Schwellwertbilder mit (siehe prepare_variation_modelprepare_variation_modelPrepareVariationModelprepare_variation_modelPrepareVariationModelPrepareVariationModel und prepare_direct_variation_modelprepare_direct_variation_modelPrepareDirectVariationModelprepare_direct_variation_modelPrepareDirectVariationModelPrepareDirectVariationModel). Dann wird die Ausgaberegion RegionRegionRegionRegionRegionregion aus allen Punkten bestimmt, die sich stark vom Modell unterscheiden, d.h. für die gilt:

Falls nur zu helle oder zu dunkle Fehler segmentiert werden sollen, kann der Operator compare_ext_variation_modelcompare_ext_variation_modelCompareExtVariationModelcompare_ext_variation_modelCompareExtVariationModelCompareExtVariationModel verwendet werden.
