【摘要】 基于遥感图像摄取过程中的特点，在模糊特征域上进行图像增强，然后引用反变换灰度图像中的熵信息进行阈值分割，最后给出了与其它两种熵阈值分割方法的比较实验．定性和定量分析结果证实了该方法在分割精度和运算速度方面所具有的优势．更多还原

【Abstract】 Based on its characteristics, the remote sensing image was enhanced on its fuzzy property domain, then the threshold was selected by use of the entropy concept in gray image. Finally, a comparision with two other threshold selection methods was investigated quantitatively and qualitatively. The experimental results show that this method can segment the object from background precisely and quickly.更多还原
