This techniquetakes images containing texts as input and tries to recognize the contained characters so the text canbe edited and saved.The example images contain one good and one bad example. The bad example suffers from lowresolution so the OCR algorithm is not able to recognize the characters correctly.Hint:You may want to increase your heap space as this processing flow needs a lot of memory. see: http://tech.knime.org/faq#q4_2 for detailsIf you need more information about other topics, browse our tutorials.
