As a kind of critical information in images and computer vision tasks, contour has a general application due to the robustness to illumination. However, it is far from meeting the current requirement because of expensive computation and noise in the real-world application. This paper proposes a novel approach of extracting contours in images. Firstly, we can obtain the salient points on the target contour by use of the accuracy property of Chord-to-point distance under combination of an ellipse model method. Then, a hyperbolic curve segment is used to fit the salient points, which can represent the target contour. The extensive experiments show that our method has better robustness and gives more exact approximation to the original target contour. Our work provides more selections for the practical application of contour completion.
