### Synthesized Data Experiments  
Using the synthetic datasets in Figure 6, quantitative comparisons can be performed. The images shown here as RGB color photos generated from the appropriate spectral bands, are all generated from hyperspectral images. Images a through f, which originate from [4; 5; 6; 7], and the processes used to synthesize them are described in Appendix A. They present varied scenes with coastal, agricultural, rural, urban, and mixed geographies. Section 3.2.2 evalutes the methods using all of the datasets in Figure 6. Section 3.2.1 focuses on Figure 6g, which was generated from AVIRIS [54] data for this paper.
