METHOD EXECUTED BY COMPUTER FOR AUTOMATICALLY RECOGNIZING TEXT IN ARABIC, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To extract a text feature appropriately in recognizing a text in Arabic.;SOLUTION: A two-dimensional array of pixels associated with pixel values each of which is expressed in a binary number is formed as a result of digitalization of a line of Arabic characters. The pixel values are expressed in a binary number. The line of Arabic characters is divided into a plurality of line images, and a plurality of cells are defined in one of the plurality of line images. Each of the plurality of cells has an adjoining pixel group. A two-value cell number is formed as a result of serialization of the pixel value of each pixel of the plurality of cells in one of the plurality of line images. A text feature vector is formed in accordance with the two-value cell number obtained from the plurality of cells in one of the plurality of line images. The text feature vector is sent to a hidden Markov model so that the line of Arabic characters is recognized.;COPYRIGHT: (C)2014,JPO&INPIT
