| Abstract: | 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. |
