【摘要】 水域是SAR图像的一个重要特征,针对SAR图像水域的检测问题,提出了一种利用形态学和信息跟踪双模式相结合的检测方法。采用形态学的开运算,提取基本的水域轮廓,再结合改进的信息编码,进行跟踪检测,进一步精确定位水域区域。实验结果表明,双模式结合的水域检测方法,可以较准确的提取SAR图像的水域区域,效果要优于单一模式的检测方法,而且跟信息熵方法相比较还提高了运算效率。更多还原

【Abstract】 To the characteristic of water area in SAR image,a two pattern combined method based on morphology and entropy algorithm is proposed to detect water area from SAR image.The first step is to detect outline of water area and reduce speckle noise by using mathematical morphology method.Then the water area is detected exactly combining improved entropy algorithm.The result of experiments show that,this method can detect water area from SAR image effectually,also can improve process speed effectively than entropy method.更多还原
