Image Processing Based OMR Sheet Scanning System

This paper aims to develop Image processing based Optical Mark Recognition sheet scanning system. Today we find that lot of competitive exams are been conducted as entrance exams. These exams consists of MCQs. The students have to fill the right box or circle for the appropriate answer to the respective questions. This is a manual process and a lot of errors can occur in the manual process such as counting mistake and many more. To avoid this mistakes OMR system is used. In this system OMR answer sheet will be scanned and the scanned image of the answer sheet will be given as input to the software system. Using Image processing we will find the answers marked to each of the 50 questions by finding the region of interest and applying template matching algorithm. Summation of the marks & displaying of total marks will be also implemented. The implementation is done using JAVA and the image processing would be done in Open CV.
