Abstract: Recognition of written texts is one of the many subfields of pattern recognition. Recognition methods are based on driving a large number of symbols. These symbol images are grouped into databases that have mostly very high prices. In order to detect a symbol, we need to detect the direction of the cell where it is located. Although it seems simple, finally we get to solve a problem of pattern recognition to obtain driving data required for similar problem, the recognition of characters. Fortunately, the new problem is simpler and it can be approached using deterministic methods.

Keywords: Pattern recognition, text recognition, image detection.
