Beschreibung

class_ndim_boxclass_ndim_boxClassNdimBoxClassNdimBoxClassNdimBox klassifiziert die Bildpunkte von mehrkanaligen Bildern. Es wird hierzu der Klassifikator ClassifHandleClassifHandleClassifHandleClassifHandleclassifHandle verwendet, der mit create_class_boxcreate_class_boxCreateClassBoxCreateClassBoxCreateClassBox erzeugt wurde. Trainiert werden kann der Klassifikator mit learn_ndim_boxlearn_ndim_boxLearnNdimBoxLearnNdimBoxLearnNdimBox oder wie bei create_class_boxcreate_class_boxCreateClassBoxCreateClassBoxCreateClassBox beschrieben. Siehe auch class_ndim_normclass_ndim_normClassNdimNormClassNdimNormClassNdimNorm.

MultiChannelImageMultiChannelImageMultiChannelImageMultiChannelImagemultiChannelImage ist ein mehrkanaliges Bild, dessen Bildpunkte klassifiziert werden sollen. D.h. es werden die Bildpunkte ausgewählt, die dem Klassifikationskriterium genügen.

Komplexität

Sei N die Anzahl der Hyperquader und A die Fläche der Eingaberegion(en), dann ist die Laufzeitkomplexität O(N,A).

Ergebnis

class_ndim_boxclass_ndim_boxClassNdimBoxClassNdimBoxClassNdimBox liefert den Wert 2 (H_MSG_TRUE), falls die Parameter korrekt sind. Für das Verhalten bzgl. der Eingabebilder und Ausgaberegionen sind die Flags 'no_object_result'"no_object_result""no_object_result""no_object_result""no_object_result", 'empty_region_result'"empty_region_result""empty_region_result""empty_region_result""empty_region_result" und 'store_empty_region'"store_empty_region""store_empty_region""store_empty_region""store_empty_region" einstellbar (siehe set_systemset_systemSetSystemSetSystemSetSystem). Gegebenenfalls wird eine Fehlerbehandlung durchgeführt.
