描述
get_params_ocr_class_knnget_params_ocr_class_knnGetParamsOcrClassKnnGetParamsOcrClassKnnGetParamsOcrClassKnnget_params_ocr_class_knn returns the parameters of an OCR
classifier that were specified when the classifier was created with
create_ocr_class_knncreate_ocr_class_knnCreateOcrClassKnnCreateOcrClassKnnCreateOcrClassKnncreate_ocr_class_knn。This is particularly useful if the
classifier was read with read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn。The output of
get_params_ocr_class_knnget_params_ocr_class_knnGetParamsOcrClassKnnGetParamsOcrClassKnnGetParamsOcrClassKnnget_params_ocr_class_knn can, for example, be used to check
whether a character to be read is contained in the classifier. For
