Description🔗

get_params_ocr_class_knnGetParamsOcrClassKnn returns the parameters of an OCR classifier that were specified when the classifier was created with create_ocr_class_knnCreateOcrClassKnn. This is particularly useful if the classifier was read with read_ocr_class_knnReadOcrClassKnn. The output of get_params_ocr_class_knnGetParamsOcrClassKnn 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_knnCreateOcrClassKnn and trainf_ocr_class_knnTrainfOcrClassKnn.

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.

Parameters🔗

Width of the rectangle to which the gray values of the segmented character are zoomed.

HeightCharacterheightCharacterheight_character (output_control) integer → (integer)HTuple (Hlong)HTuple (int / long)intHtuple (Hlong)

Height of the rectangle to which the gray values of the segmented character are zoomed.

Interpolationinterpolationinterpolation (output_control) string → (string)HTuple (HString)HTuple (string)strHtuple (char*)

Interpolation mode for the zooming of the characters.

Featuresfeaturesfeatures (output_control) string(-array) → (string)HTuple (HString)HTuple (string)Sequence[str]Htuple (char*)

Features to be used for classification.

Characterscharacterscharacters (output_control) string-array → (string)HTuple (HString)HTuple (string)Sequence[str]Htuple (char*)

Characters of the character set to be read.

Preprocessingpreprocessingpreprocessing (output_control) string → (string)HTuple (HString)HTuple (string)strHtuple (char*)

Result🔗

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