Effective ellipse detection method in limited-performance embedded system for aerospace application

Up to present, there have been numerous articles on ellipse detection. However, it is still a great challenge especially for embedded application with restricted available computing and memory resources. To handle this problem, a novel and effective method is presented for ellipse detection. The method consists of two main steps: extraction of elliptic edge contours and edge contours grouping. These two steps are integrated to improve the accuracy and speed of the method. Finally, the aim of this method is to process high-resolution image for embedded system, which needs fast and accurate ellipse detection with limited computational and memory resources.
