Beschreibung

Die Prozedur berechnet aus einer Co-Occurence-Matrix (CoocMatrixCoocMatrixCoocMatrixCoocMatrixCoocMatrixcoocMatrix) die Energie (EnergyEnergyEnergyEnergyEnergyenergy), Korrelation (CorrelationCorrelationCorrelationCorrelationCorrelationcorrelation), lokale Homogenität (HomogeneityHomogeneityHomogeneityHomogeneityHomogeneityhomogeneity) und den Kontrast (ContrastContrastContrastContrastContrastcontrast).

cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix berechnet aus dem Teil der mit gen_cooc_matrixgen_cooc_matrixGenCoocMatrixgen_cooc_matrixGenCoocMatrixGenCoocMatrix generierten Eingabe-Matrix, der der mit dem dortigen Parametern LdGray und Direction angegebenen Richtungsmatrix entspricht, die Grauwertmerkmale nach folgenden Formeln:

Energie:

Korrelation:
lokale Homogenität:
Kontrast:

Achtung

Die Region des Eingabebildes wird nicht beachtet.

Ergebnis

cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix liefert den Wert 2 (H_MSG_TRUE), falls ein Bild mit definierten Grauwerten 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>) festgelegt. Gegebenenfalls wird eine Fehlerbehandlung durchgeführt.
