do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvm — Classify multiple characters with an SVM-based OCR classifier.
do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvmDoOcrMultiClassSvm computes the best class for each of
the characters given by the regions CharacterCharacterCharacterCharactercharacter and the gray
values ImageImageImageImageimage with the SVM-based OCR classifier
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle and returns the classes in ClassClassClassClassclassVal. In
contrast to do_ocr_single_class_svmdo_ocr_single_class_svmDoOcrSingleClassSvmDoOcrSingleClassSvmDoOcrSingleClassSvm,
do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvmDoOcrMultiClassSvm can classify multiple characters in
one call, and therefore typically is faster than a loop that uses
do_ocr_single_class_svmdo_ocr_single_class_svmDoOcrSingleClassSvmDoOcrSingleClassSvmDoOcrSingleClassSvm to classify single characters.
However, do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvmDoOcrMultiClassSvm can only return the best
class of each character. Before calling
do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvmDoOcrMultiClassSvm, the classifier must be trained with
trainf_ocr_class_svmtrainf_ocr_class_svmTrainfOcrClassSvmTrainfOcrClassSvmTrainfOcrClassSvm.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
Characters to be recognized.
Gray values of the characters.
Handle of the OCR classifier.
Result of classifying the characters with the
SVM.
If the parameters are valid the operator
do_ocr_multi_class_svmdo_ocr_multi_class_svmDoOcrMultiClassSvmDoOcrMultiClassSvmDoOcrMultiClassSvm returns the value 2 (H_MSG_TRUE). If
necessary, an exception is raised.
