Abstract

Recognition of characters is a problem in image recognition. Contours are often used. The contour of a character can be expressed with much less data than the original character. There are a suit of algorithms that represent contours by connected quadratic curves. With this representation, corners of characters can be detected by locating those corner points. This project will emphasize on the implementation of those algorithms: including the contour tracking, segmentation and how quadratic curves are obtained from the contour. It is a java application and has a GUI interface. You can select an image, run the algorithm and see the simulation steps.
