提出一种基于边缘检测的快速溢油信息提取方法,首先对溢油图像进行ROA(radio of average)边缘检测,根据检测结果进行AOI(area of interest)提取,然后使用改进的Weibull-CFAR检测算法对AOI进行溢油检测,并与全局CFAR检测结果进行对比。实验结果证明,所提出的方法对于非均匀灰度SAR图像溢油检测准确性较好、效率较高,特别适用于大图像的快速溢油检测。 更多还原

【Abstract】 The side-look imaging of SAR (Synthetic Aperture Radar) may result in the pockety density, so we can not get a satisfying result by using CFAR (constant false alarm rate) detection on the whole image. To improve the oil detection capability, we propose a new oil detection method based on edge detection in this paper. First, the AOI (area of interest) of oil is detected through radio edge detection, then an improved Weibull-CFAR detector is applied to the AOI. Comparing with the whole CFAR detect... 更多还原
