一种四叉树和测地线活动轮廓模型相结合的海陆影像分割方法

海陆影像分割对于后续的海岸线提取、潮间带地形反演、海岸演化状况分析等都具有十分重要的意义。本文在分析了四叉树、测地线活动轮廓（GAC）模型和Canny边缘检测算子等在海陆影像分割中优缺点的基础上，提出了一种四叉树、Canny算子和GAC模型相结合的海陆影像分割方法。该方法综合利用上述各方法的优点，将Canny算子边缘检测结果融入到基于四叉树初分割的GAC模型中，重构边界停止函数，演化水平集方程，实现海陆影像分割。试验结果表明，该方法具有海陆影像分割速度快、精度高、可靠性强和自动化程度高等优点，对于弱边缘以及严重凹陷边缘，都能实现自动和准确分割。...

Island and coastal image segmentation is of great importance for the subsequent coastline extraction, terrain inversion for intertidal zone, analysis of the situation for shore evolution, and so on. Firstly, the advantages and disadvantages of quadtree, geodesic active contour （GAC） model and Canny edge detector used in the island and coastal image segmentation are analyzed. Secondly, an island and coastal image segmentation method is proposed by integrating quadtree, GAC model and Canny edge detector. The advantages of these three kinds of method are taken in the method proposed in this paper. The method introduces the results of Canny edge detector into edge in
