CheckIt - A low cost mobile OMR system

This paper describes CheckIt: a mobile phone based optical mark recognition(OMR) system which is used for automatic checking of the user response sheets. It exploits prior information about the OMR sheet layout, which helps in achieving high speed and accuracy. The system incorporates following interdependent modules: (i) computer vision and image processing; (ii) computer communication and networking; (iii) database and (iv) user interface. The back end is developed in Python and OpenCV library while the front end is made using HTML and Android. The overall system cost is low as; 1. software is developed using open-source technology; 2. it does not necessitate scanning hardware. The desirability and viability aspect of the system development is done based on extensive market survey and after interviewing several stake holders.
