Maximum entropy approach to temperature/emissivity separation

Temperature and emissivity separation applied to multispectral Thermal Infrared (TIR) images provides relevant parameters for atmosphere and soil characterization Earth surface provides temperature and emissivity, relevant parameters for Earth observation studies. The retrieval of both temperature and emissivity is an ill-posed problem admitting infinite solutions, being the number of unknowns greater than available measurements. In this work the Maximum Entropy Temperature and Emissivity Separation (MaxEnTES) algorithm is presented, after summarizing the physical implications of the information theory.
