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

Table 2

Evaluation of the difference between expected background radiance and estimated background radiance, using one of the three methods used in this paper. The first table presents the root mean square of the brightness temperature error (), while the second summarizes the results in terms of the relative root mean square error on radiance ().
