Optical Mark Reader (OMR) Based on OpenCV framework The goal of this project is to write an algorithm to process an image on camera (answer sheet) and detect filled bubbles. The algorithm will deal with image resolution and inclination angle due to scanner manipulation. The algorithm will work with all scanned images coming from any ordinary camera(or webcans). In attached file, you will have an model of Answer sheet in PDF format. You must print it, scan it and process image to retrieve scanned bubbles. In Answer model sheet, you will have two main region of interest. The first one called qrcode is used to store the unique identifier of the student. The second one is used to store the answer of question. For example, for question one, if the correct result is "A", the student should mark bubble ("1,A") or more than one answer like ("1,A,C") the source code have to be commented Tools to use - OpenCV to process videos ( [login to view URL]) - pyton as programming language - PostgreSQL as database engine if give working also on android (APK) the money rise to in 500 dollars(USD) you can see a example on this link [login to view URL]
