Description
The operation creates a set of character samples used to train OcrMlpModel in the TrainOcr_MLP filter. Consecutive letters in inCharacters correspond to consecutive regions in inCharacterRegions.
Examples
Description of usage of this filter can be found in examples and tutorial: OCR Read Number, OCR Read Number (SVM).
Remarks
The length of inCharacters must be equal to the size of the inCharacterRegions array.
