【摘要】 遥感图像去云的关键技术是云团及其阴影的检测技术。通常情况下,云团在图像中是亮度值最高的目标,其形状呈不规则团状,而阴影是图像中亮度较低的目标。基于上述出发点,本文提出的算法包括两个步骤:云阴检测、对比融合。实验表明,本算法对遥感图像去云具有明显的效果。更多还原

【Abstract】 The key technology of removing cloud from the sensing images is the detection of the cloud and its shadow. In general case,the cloud in the images is the target which the brightness value is high, and its shape is abnormity group. The shadow in the images is the target which the brightness value is low. The algorithm includes two steps-the cloud detection,the contrast data fusion. The result shows the algorithm is effective.更多还原
