Background Radiance Estimation for Gas Plume Quantification for Airborne Hyperspectral Thermal Imaging

Figure 16

Comparison of different radiances at the ethylene absorptive band (), along a horizontal cross section containing some plume-present pixels. The red curve stands for the on-plume radiances; the green dotted one is the expected background radiances. The cyan, blue, and magenta curves represent, respectively, the background radiances estimated by the SB, CB, and CSB methods.
