Hyperspectral Data Processing: Algorithm Design and Analysis

15.3 Synthetic Image Experiments

The synthetic image has the five mineral spectral signatures, A, B, C, K, M, marked by circles in Figure 1.12(b) are used to simulate 25 panels shown in Figure 15.1 with five panels in each row simulated by the same mineral signature and five panels in each column having the same size. Among 25 panels are five pure-pixel panels for each row in the first column and five pure-pixel panels for each row in the second column, the five -mixed pixel panels for each row in the third column and both the five subpixel panels for each row in the fourth column and the fifth column where the mixed and subpanel pixels are simulated according to legends in Figure 15.1. So, a total of 100 pure pixels (80 in the first column and 20 in second column), referred to as endmember pixels are simulated in the data by the five endmembers, A, B, C, K, M.

These 25 panels are then inserted in a synthetic image with size ...
