Description🔗

get_params_ocr_class_svmGetParamsOcrClassSvm returns the parameters of an OCR classifier that were specified when the classifier was created with create_ocr_class_svmCreateOcrClassSvm. This is particularly useful if the classifier was read with read_ocr_class_svmReadOcrClassSvm. The output of get_params_ocr_class_svmGetParamsOcrClassSvm can, for example, be used to check whether a character to be read is contained in the classifier. For a description of the parameters, see create_ocr_class_svmCreateOcrClassSvm.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

Result🔗

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