| 摘 要： | 提出一种基于扩展CENTRIST纹理算子的遥感场景分类方法.它由更多邻域规模的三个子方案组成,不仅继承了CENTRIST的优点,而且编码了更多不同纹理的局部结构信息.通过三种不同模式的纹理算子来提取多通道图像纹理特征,通过谱回归判别分析进行分类识别.提出能够捕获多通道图像中互补信息的多通道eCT融合机制,以获得更高的分...

| Abstract: | This paper presents a remote sensing scene classification method based on extended CENTRIST(eCT)texture operator.It consists of three sub-schemes with more neighborhood sizes,and it not only inherits the advantages of CENTRIST,but also encodes the local structure information of more different textures.This method extracted multi-channel image texture features by three different patterns of texture operators,and then used spectral regression discriminant analysis for classification and recognition.In order to obtain higher classification accuracy,a multi-channel eCT fusion mechanism was proposed,which could capture the complementary information in multi-channel images.The experimental results on UC Merced database show that the results obtained by this method are better than CENTRIST,and the robustness is higher. |
