get_support_vector_ocr_class_svm — Return the index of a support vector from a trained OCR classifier that is based on support vector machines.
The operator get_support_vector_ocr_class_svm maps support vectors of a trained SVM-based OCR classifier (given in OCRHandle) to the original training data set. The index of the SV is specified with IndexSupportVector. The index is counted from 0, i.e., IndexSupportVector must be a number between 0 and IndexSupportVectors - 1, where IndexSupportVectors can be determined with get_support_vector_num_ocr_class_svm. The index of this SV in the training data is returned in Index. get_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_trainf. The value returned in Index must be incremented by 1 and can then be used to select the support vectors with select_obj from the training characters. If more than one train file has been used in trainf_ocr_class_svm Index behaves as if all train files had been merged into one train file with concat_ocr_trainf.
Number of stored support vectors.
Index of the support vector in the training set.
If the parameters are valid the operator get_support_vector_ocr_class_svm returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
