| 摘 要： | 在总结分析相关工作的基础上,提出了一种基于Euler Spiral修复认知轮廓中缺失边界的算法。该算法首先通过活动轮廓模型进行认知轮廓的初始定位,将视觉的预测性插值问题转化为中间插值问题,然后结合取向估计和Euler Spiral修复缺失的轮廓边界,取代了活动轮廓模型的迭代优化过程。对典型认知轮廓图形和遥感图像的实验结果验证了算法的有效性。

| Abstract: | This paper proposes an algorithm based on Euler Spiral to complete the missing boundary in illusory contour.By this method,an active contour model is first initialized and extended turning the predictive visual interpolation one to a pure interpolation problem;then orientation estimation and Euler Spiral are combined to complete the missing boundary.The experimental results on illusory contour figures and a remote sensing image show the efficiency of the algorithm. |
