The Grading Multiple Choice Tests System via Mobile Phone using Image Processing Technique

Grading devices are expensive causing budget waste, in addition some are difficult to use. Therefore, an objective test grading system via Android mobile phone was developed to save cost and time in grading. The system uses image processing technique developed by Java. A camera on a mobile phone wa...
