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

Figure 10

Comparison of background radiance estimation methods, for four different pixels through the plume. The red curves stand for the on-plume radiances; the dotted green ones are the real background radiances. The cyan, blue, and magenta curves represent, respectively, the background radiance estimated by the SB, CB, and CSB methods. (a) Results for pixel 1 (brown sandy loam), (b) results for pixel 2 (asphalt), (c) results for pixel 3 (aluminum), and (d) results for pixel 4 (copper).
