Signatur
Beschreibung
classify_image_class_lutclassify_image_class_lutClassifyImageClassLutClassifyImageClassLutClassifyImageClassLutclassify_image_class_lut führt auf einem mehrkanaligen Byte-Bild
ImageImageImageImageimageimage eine Pixelklassifikation anhand einer Look-Up-Table (LUT)
ClassLUTHandleClassLUTHandleClassLUTHandleClassLUTHandleclassLUTHandleclass_luthandle durch. Der Operator kann

classify_image_class_mlpclassify_image_class_mlpClassifyImageClassMlpClassifyImageClassMlpClassifyImageClassMlpclassify_image_class_mlp und
classify_image_class_svmclassify_image_class_svmClassifyImageClassSvmClassifyImageClassSvmClassifyImageClassSvmclassify_image_class_svm ersetzen, was die Klassifikation
deutlich beschleunigt, weil die entsprechende Klasse nicht in jedem
Bildpunkt extra berechnet werden muss, da alle möglichen Antworten des GMM,
KNN, MLP bzw. SVM in der LUT gespeichert sind. Dieser LUT Klassifikator muss vor
der Verwendung von classify_image_class_lutclassify_image_class_lutClassifyImageClassLutClassifyImageClassLutClassifyImageClassLutclassify_image_class_lut durch den entsprechend
trainierten Klassifikator mit create_class_lut_gmmcreate_class_lut_gmmCreateClassLutGmmCreateClassLutGmmCreateClassLutGmmcreate_class_lut_gmm,

werden. Für die Klassifizierung sind die in create_class_gmmcreate_class_gmmCreateClassGmmCreateClassGmmCreateClassGmmcreate_class_gmm,

von Bedeutung: Das Byte-Bild ImageImageImageImageimageimage muss die selbe Anzahl von
Kanälen besitzen, wie in NumInputNumInputNumInputNumInputnumInputnum_input, NumFeaturesNumFeaturesNumFeaturesNumFeaturesnumFeaturesnum_features bzw.
NumDimNumDimNumDimNumDimnumDimnum_dim spezifiziert wurde. Als Ausgabe werden in
ClassRegionsClassRegionsClassRegionsClassRegionsclassRegionsclass_regions NumOutputNumOutputNumOutputNumOutputnumOutputnum_output bzw. NumClassesNumClassesNumClassesNumClassesnumClassesnum_classes Regionen
als Ergebnis der Pixelklassifikation zurückgegeben.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Automatisch parallelisiert auf interner Datenebene.

Beispiel (HDevelop)
read_image (Image, 'patras')
gen_rectangle1 (Sea, 10, 10, 120, 270)
gen_rectangle2 (Deck, [170,400], [350,375], [-0.56192,-0.75139], \
[64,104], [26,11])
union1 (Deck, Deck)
gen_rectangle1 (Walls, 355, 623, 420, 702)
gen_rectangle2 (Chimney, 286, 623, -0.56192, 64, 33)
concat_obj (Sea, Deck, Classes)
concat_obj (Classes, Walls, Classes)
concat_obj (Classes, Chimney, Classes)
*
* create MLP classifier and train it with sample classes
create_class_mlp (3, 3, 4, 'softmax', 'principal_components', 3, \
42, MLPHandle)
add_samples_image_class_mlp (Image, Classes, MLPHandle)
train_class_mlp (MLPHandle, 200, 1, 0.01, Error, ErrorLog)
*
* create the LUT classifier
create_class_lut_mlp (MLPHandle, [], [], ClassLUTHandle)
*
* classify the image with the LUT
classify_image_class_lut (Image, ClassRegions, ClassLUTHandle)
Ergebnis
Sind die Parameterwerte korrekt, dann liefert
classify_image_class_lutclassify_image_class_lutClassifyImageClassLutClassifyImageClassLutClassifyImageClassLutclassify_image_class_lut den Wert 2 (H_MSG_TRUE). Gegebenenfalls wird
eine Fehlerbehandlung durchgeführt.
