Name

get_support_vector_ocr_class_svmT_get_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm — Return the index of a support vector from a trained OCR classifier that is based on support vector machines.

Signature

Description

The operator get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm maps support vectors of a trained SVM-based OCR classifier (given in OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle) to the original training data set. The index of the SV is specified with IndexSupportVectorIndexSupportVectorIndexSupportVectorIndexSupportVectorindexSupportVectorindex_support_vector. The index is counted from 0, i.e., IndexSupportVectorIndexSupportVectorIndexSupportVectorIndexSupportVectorindexSupportVectorindex_support_vector must be a number between 0 and NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors - 1, where NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors can be determined with get_support_vector_num_ocr_class_svmget_support_vector_num_ocr_class_svmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmGetSupportVectorNumOcrClassSvmget_support_vector_num_ocr_class_svm. The index of this SV in the training data is returned in IndexIndexIndexIndexindexindex. get_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm can, for example, be used to visualize the support vectors. To do so, the train file that has been used to train the SVM must be read with read_ocr_trainfread_ocr_trainfReadOcrTrainfReadOcrTrainfReadOcrTrainfread_ocr_trainf. The value returned in IndexIndexIndexIndexindexindex must be incremented by 1 and can then be used to select the support vectors with select_objselect_objSelectObjSelectObjSelectObjselect_obj from the training characters. If more than one train file has been used in trainf_ocr_class_svmtrainf_ocr_class_svmTrainfOcrClassSvmTrainfOcrClassSvmTrainfOcrClassSvmtrainf_ocr_class_svm IndexIndexIndexIndexindexindex behaves as if all train files had been merged into one train file with concat_ocr_trainfconcat_ocr_trainfConcatOcrTrainfConcatOcrTrainfConcatOcrTrainfconcat_ocr_trainf.

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_support_vector_ocr_class_svmget_support_vector_ocr_class_svmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmGetSupportVectorOcrClassSvmget_support_vector_ocr_class_svm returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
