Ren Jin, Hafiz Muhammad Owais, Tao Song, Defu Lin · 2018
Ellipse detection is an important task in machine vision and can be used to solve other high-level visual problems. In the past, many studies have been conducted by researchers at high precision ellipse fitting, but most of the proposed solutions are not fast enough to be applied in real-time detection for larger images or with limited hardware resources. This paper improves the accuracy of ellipse detection by improving the candidate ellipse scoring method and geometric constraints. Combined with ellipse fitting algorithm, the proposed method can perform real-time ellipse and semi ellipse detection. The efficiency of the algorithm is proven by using three popular datasets which shows the state of the art ellipse and semiellipse detection performance.
