Abstract :

Registration is the fundamental task in image processing; it is primarily used to compare two or more images taken over the years. A broad range of techniques have been developed for various types of data and problems. Basically, there are two broad categories of image registration; (i) intensity based registration and (ii) feature based registration. This paper presents an Intensity-Based Image registration method that align two or more answer sheets of multiple choice test together for the purpose of optical mark recognition. The objective of image registration is to bring the target image into alignment with the reference object by applying spatial transformation to the test object image. The sample data used in this work consist of Template (fixed) image and sample (moving) images scanned using ordinary scanner with a low resolution of 200 dpi. An average registration accuracy of 97% is recorded at a processing speed of 5 seconds per sample.
