Abstract
Competitive exams plays a key role in most of the professional courses. These competitive exams generally consists of multiple choice questions. The Optical Mark Reader can be used for calculating examination scores from these answer sheets. Image Processing is the processing of images to get the enhanced images or to extract useful information from it. By using this technique, we develop a system based on PC-type microcomputer which is connected to an image scanner. Initially the true answer keys are stored in the database. The scanned sheets are sent to the system which is pre-processed using noise reduction and skew detection techniques, which is then compared with the true answer keys for the generation of results. Based on this result, rank is generated and SMS is sent to the respective students.
