Abstract:
1. A computer-implemented method for text data recognition, comprising obtaining an image file from scanning device or from other source, preliminarily assigning at least a part of a list of applied supplementary data types and an order of application of the supplementary data types in the list, said list comprising, in order of application: preliminarily assigning of an accuracy estimation for each type of supplementary data, performing one or more line-to-fragments parsing versions by reliably recognized spaces, said fragments presumably comprising single word images, building of line partition graph (hereinafter LPG) for each line fragment, said graph describing fragment-to-graphemes parsing versions, said graphemes presumably comprising character images, performing single graphemes recognition, using two or more classifiers of different types, assigning each said grapheme recognition version accuracy estimation, interpretation of grapheme recognition version as a character version, performing at least the following steps: separation of previously mistakenly combined elements.
