The application for exams grading and evaluation on multiple choice tests using image processing and data mining technique

Abstract

Multiple-choice questions exams play a vital role in most of the professional courses from Primary School to High School not only in Vietnam but all over the world. As a part of multiple-choice questions exams, grading usually takes a lot of time and effort for teachers to score students answers sheets. Therefore, we decide to develop The Application for Exams Grading and Evaluation on Multiple Choice Tests Using Image Processing and Data Mining Technique to be considered as a cost and time-effective solution. This solution not only saves time and money for teachers to grade multiple-choice questions exams manually but also can give teachers useful insights that help teachers make data-driven decisions on improving the quality of exams and lectures. After researching, we have developed a complete algorithm of application and started to implement the first two modules, which are Pre-Process and Grading Exams. The obtained results have been tested and have been proved working under different conditions including capture perspectives, capture angles, and brightness conditions.
