Some charactistical aspects of MarkRead-a software package for automatic mark data entry

Automatic data entry plays an important role for improving speed and effectiveness for information technology. In order to recognize forms and join results into a database, it is necessary to correctly isolate geometrical objects and match forms with a pattern. Therefore, this paper presents some difficult problems of optical mark recognition such as detecting image skew, margins and basic geometrical objects, which are solved in the process of developing MarkRead, a software package for automatic mark data entry.
