Оцінка інформативності ознак для розпізнавання нестандартних символів

Abstract

In this work the evaluation of the information content of the selected features type for character recognition of non-standard characters in the form of metal-engraved digit 0-9 and the efficiency of their selection methods are investigated. As the features the center of gravity of the symbol, the total center of gravity of the light parts of the symbol, the vector of coordinates of the intersection of the symbol with the standard shape are selected. From the results of the study it is concluded that the most effective is the recognition on the basis of the third feature type - the vector of the character intersection coordinates with the standard shape.
