基于水平集的海岛(礁)提取

Sea Island and Reef Extraction Based on Level Set

提出了适合航空影像区域分割的水平集运算策略,将原始影像首先进行格网分类,对分类后的海岸线格网进行水平集运算提取精确海岛(礁)边缘,并采用多核编程策略提高运算效率。实验表明该方案效果理想,能够正确提取海岛(礁)区域。

This paper puts forward level set calculation strategy suitable for aerial image segmentation, which grid - classifies original image and execute level set calculation to the classified coast line grid to extract sea island or reef borderline utilizing multi - core programming strategy to improve calculation efficiency. Experiments show that the plan reaches an ideal result and can extract the sea island and reef area correctly.
