Beschreibung

Der Aufruf von cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage entspricht der Hintereinanderausführung von gen_cooc_matrixgen_cooc_matrixGenCoocMatrixgen_cooc_matrixGenCoocMatrixGenCoocMatrix und cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix. Wenn mehrere Richtungsmatrizen der Co-Occurrence-Matrix hintereinander ausgewertet werden sollen, ist es günstiger, die Matrix mit gen_cooc_matrixgen_cooc_matrixGenCoocMatrixgen_cooc_matrixGenCoocMatrixGenCoocMatrix zu erstellen und danach cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix für die Ergebnismatrix aufzurufen. Bei dem Parameter DirectionDirectionDirectionDirectionDirectiondirection wird die Richtung der Nachbarschaft in Winkel oder 'mean'"mean""mean""mean""mean""mean" übergeben. Bei 'mean'"mean""mean""mean""mean""mean" wird der Mittelwert aller vier Richtungen berechnet.

Achtung

Der Operator cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage berücksichtigt nur die mittels RegionsRegionsRegionsRegionsRegionsregions übergebenen Regionen und ignoriert jede Domäne, die zuvor für das Eingabebild ImageImageImageImageImageimage festgelegt wurde.

Ergebnis

cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage liefert den Wert 2 (H_MSG_TRUE), falls ein Bild mit definierten Grauwerten ('byte'"byte""byte""byte""byte""byte") eingegeben wird und die Parameter korrekt sind. Das Verhalten bei leerer Eingabe (keine Eingabebilder) wird mit set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>), das bei leerer Region mit set_system(::'empty_region_result',<Result>:)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>) festgelegt. Gegebenenfalls wird eine Fehlerbehandlung durchgeführt.
