Zusammenfassung:A method, medium, and system extracting text, including filtering a text domain image using a stroke filter, determining a color polarity of the text by using a response value of the stroke filter, binarizing the response value of the stroke filter, and expanding a local domain by using a binary domain generated by the binarization.
