Name
get_support_vector_num_ocr_class_svmT_get_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmget_support_vector_num_ocr_class_svm — Return the number of support vectors of an OCR classifier.
Signature

Description
get_support_vector_num_ocr_class_svmget_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmget_support_vector_num_ocr_class_svm returns in
NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors the number of support vectors that are
stored in the support vector machine (SVM) given by
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle. get_support_vector_num_ocr_class_svmget_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmget_support_vector_num_ocr_class_svm
should be called before the labels of individual support vectors are
read out with get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm, e.g., for
visualizing which of the training data become a SV (see
get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm). The number of SVs in
each classifier is listed in NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVMnum_svper_svm. The reason that
its sum differs from the number obtained in
NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors 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.
