Name
get_support_vector_num_ocr_class_svmT_get_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvm — Return the number of support vectors of an OCR classifier.
Signature
Description
get_support_vector_num_ocr_class_svmget_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvm returns in
NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectors the number of support vectors that are
stored in the support vector machine (SVM) given by
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle. get_support_vector_num_ocr_class_svmget_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvm
should be called before the labels of individual support vectors are
read out with get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvm, e.g., for
visualizing which of the training data become a SV (see
get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvm). The number of SVs in
each classifier is listed in NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVM. The reason that
its sum differs from the number obtained in
NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectors is that SV evaluations are reused
throughout different binary sub-SVMs.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

Result
If the parameters are valid the operator
get_sample_num_class_svmget_sample_num_class_svmGetSampleNumClassSvmGetSampleNumClassSvmGetSampleNumClassSvm returns the value 2 (H_MSG_TRUE). If
necessary, an exception is raised.
