| 1. | Two indexes was calculated to estimate the best bands union for color combination , one is optimum index factor ( oif , the sum of standard deviation divided by the sum of correlation coefficient . ) , the other is the determinant of the co - variance matrix . it can be seen from the result that for color combination the original optimal bands were tm 4 , 3 , 7 and tm 4 , 3 , 5 , the best mixed images were mnf1 , br and ndvi
以协方差矩阵行列式值和最佳指数值(组合波段标准差之和除以相关系数之和)为评价标准，得出对于tm原始波段而言，最佳的彩色合成组合是tm4 、 3 、 7和tm4 、 3 、 5 ；综合几种变换图像的彩色合成的最佳组合是mnf1 、 br 、 ndvi 。 |
