对高光谱图像（HxWxC）的通道两两计算相关系数，然后会得到一个C×C的矩阵，然后将这个矩阵用伪彩色可视化出来便得到图6中的样子。

非常感谢您的及时回复！是采用和计算CxC维度的attention类似的方式吗。就是CxHW @ HWxC 然后得到一个CxC的矩阵吗？

不是，是计算两个矩阵的相关系数。一个通道是一个矩阵。

好的 再次感谢您的耐心回复！ 请问相关系数是采用什么方式计算的。

这个可以搜一下python或pytorch有关的库。百度谷歌一搜就有。

我也尝试做了一下光谱相关性矩阵的可视化。发现MST论文fig6的相关性矩阵是场景5的，但是论文中展示的RGB是场景4的，会不会是索引从0开始而没有加1
