Short description🔗

info_ocr_class_boxInfoOcrClassBoxInfoOcrClassBoxinfo_ocr_class_boxT_info_ocr_class_box — Get information about an OCR classifier.

Warning🔗

info_ocr_class_boxInfoOcrClassBox is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM or CNN based operators instead.

Description🔗

The operator info_ocr_class_boxInfoOcrClassBox returns some information about an OCR classifier. The parameters are equivalent to those of create_ocr_class_boxCreateOcrClassBox. The parameters WidthMaxCharwidthMaxCharwidth_max_char and HeightMaxCharheightMaxCharheight_max_char indicate the extension of the largest trained character. These values can be used to control the segmentation.

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.

printf("Characters:    ")\;
for (i=0\; i<length_tuple(Characters)\; i++)
printf("     %d %s\n",i,get_s(Characters,i))\;

Result🔗

The operator info_ocr_class_boxInfoOcrClassBox always returns 2 (H_MSG_TRUE).
