Abstract

In this article, a system that allows optical recognition of characters in the Colombian national identity card is presented. The system is shaped by an image acquisition algorithm, by running drivers over Windows, working together with a methodology that does OCR by eliminating of the holographic background that is the mean trouble in this problem. Performance of this methodology was measured through testing with a data base of 34 identity cards. A 92.6% of success in character recognition was obtained.
