1. A method for identifying characters in a character string image, the method comprising:
(i) applying a first OCR engine to provide an identification of characters of at least a first type of characters and zones of at least a second type of characters in the character string image, (ii) applying on the zones of the at least second type of characters a second OCR engine to provide an identification of characters of a second type of characters, and (iii) combining the characters identified by the first OCR engine and by the second OCR engine to obtain the identification of the characters of the character string image, wherein the first OCR engine comprises a segmentation of the character string image into segmentation parts, and comprises, for each segmentation part the steps of (a) applying a first character classification to provide a first plurality of hypotheses on an at least one character represented by the segmentation part 351 and a first plurality of probabilities associated with the hypotheses, (b) verifying if the first plurality of hypotheses satisfies at least one condition, (c) if at least one condition is satisfied, applying a second character classification to provide a second plurality of hypotheses on the at least one character represented by the segmentation part and a second plurality of probabilities associated with the hypotheses. |
