Abstract
The Optical Mark Recognition (OMR) is very popular with universities for the reading of multiple-choice questions. In this article, we presented a software system for processing surveys at the Vietnam National University of Agriculture based on digital image processing. This software was built using MATLAB and easy to use. The surveys were digitized using a scanner and sent to the software tool. In this study, we tested more than 170 surveys of nine different types. The software tool correctly detected all the valid answers. It was also able to detect all questions with no or multiple marks.
