| 摘 要： | 首次提出了一种多波段组合的孤立噪声去除方法.文章在对图像进行中值滤波处理之前,先进行门限法的孤立噪声初步定位,设定孤立噪声为候选点;然后结合多波段图像数据对候选孤立噪声进行最终定位,只有当像元判断为真实的孤立噪声时,进行中值滤波处理;最后以中国一颗传输型卫星图像为例,检验了算法的有效性. |

| Abstract: | A method of removing isolated noises based on multi-band combination was firstly presented.In this paper,the isolated noises were preliminarily positioned and set as candidate by threshold method before median filtering;then these candidate-isolated noises were checked combining multi-band image information.If the candidate-isolated noises were real isolated noises,they would be removed by median filter.In the end,we took the domestic transmission satellite as example,and checked the validity of this method... |
