reduce_ocr_class_svmreduce_ocr_class_svmReduceOcrClassSvmreduce_ocr_class_svmReduceOcrClassSvmReduceOcrClassSvm — Approximate a trained SVM-based OCR classifier by a reduced SVM.
reduce_ocr_class_svmreduce_ocr_class_svmReduceOcrClassSvmreduce_ocr_class_svmReduceOcrClassSvmReduceOcrClassSvm reduces the classification time of an
SVM based OCR classifier OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleOCRHandle by returning a reduced
copy of it in OCRHandleReducedOCRHandleReducedOCRHandleReducedOCRHandleReducedOCRHandleReducedOCRHandleReduced. The parameters
MethodMethodMethodMethodMethodmethod, MinRemainingSVMinRemainingSVMinRemainingSVMinRemainingSVMinRemainingSVminRemainingSV and MaxErrorMaxErrorMaxErrorMaxErrorMaxErrormaxError have
the same meaning as in reduce_class_svmreduce_class_svmReduceClassSvmreduce_class_svmReduceClassSvmReduceClassSvm and are described
there. Please note that classification time can also be
significantly reduced with a preprocessing step in
create_ocr_class_svmcreate_ocr_class_svmCreateOcrClassSvmcreate_ocr_class_svmCreateOcrClassSvmCreateOcrClassSvm, which possibly introduces less
errors.
- Multithreading type: exclusive (runs in parallel only with independent operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Minimum number of remaining SVs.
Default value: 2
Suggested values: 2, 3, 4, 5, 7, 10, 15, 20, 30, 50
Restriction: MinRemainingSV >= 2
Maximum allowed error of reduction.
Default value: 0.001

SVMHandle of reduced OCR classifier.
If the parameters are valid the operator
reduce_ocr_class_svmreduce_ocr_class_svmReduceOcrClassSvmreduce_ocr_class_svmReduceOcrClassSvmReduceOcrClassSvm returns the value 2 (H_MSG_TRUE). If necessary,
an exception is raised.
