A segmentation algorithm is presented within a text recognition system. The output of an OCR system and the contextual analysis based on the dictionary method are used jointly to segment a line of text. A distance definition is introduced between a pattern representing a bitmap with the input text line and a string representing an entry of the dictionary. The algorithm is used in a system that aims at recognizing a book by reading the scripts on its cover and by comparing the recognized text with a stored database. Preliminary experiments are presented for both the line recognition and book recognition task.

Abstract
A segmentation algorithm is presented within a text recognition system. The output of an OCR system and the contextual analysis based on the dictionary method are used jointly to segment a line of text. A distance definition is introduced between a pattern representing a bitmap with the input text line and a string representing an entry of the dictionary. The algorithm is used in a system that aims at recognizing a book by reading the scripts on its cover and by comparing the recognized text with a stored database. Preliminary experiments are presented for both the line recognition and book recognition task.File in questo prodotto:
