OCR
ExtractText

Ready-to-use tool for extracting and splitting character to single characters.

OCR
ExtractText2

Ready-to-use tool for extracting and splitting text elements to single characters.

OCR
GroupRegionsByLines

Splits an array of blobs by distance to computed base lines.

OCR
LoadOcrMlpModel

OCR
ReadText

Ready-to-use tool for reading text from images using the OCR technique.

OCR
RecognizeCharacters

Classifies input regions into characters. Based on the Multi-Layer Perceptron model.


Usually the last, yet the most important step of optical character recognition or verification.

OCR
SaveOcrMlpModel

Saves serialized OcrMlpModel object as AVDATA file.

OCR
SaveOcrModel

Saves serialized OcrMlpModel object as AVDATA file.

OCR
SaveOcrSvmModel

OCR
SplitRegionIntoExactlyNCharacters

Splits the input region into a fixed-size array of regions corresponding to individual characters.


Text segmentation when the number of characters is known, usually followed by a RecognizeCharacters filter.

OCR
SplitRegionIntoMultipleCharacters

Splits the input region into an array of regions corresponding to individual characters.


Text segmentation when the number of characters is unknown, usually followed by a RecognizeCharacters filter.

OCR
TrainOcr_MLP

Trains an OCR multilayer perceptron classifier.

OCR
TrainOcr_SVM
