Maximum Entropy Temperature-Emissivity Separation in the TIR spectral range using the MaxEnTES algorithm

► Simultaneous retrieval of both target temperature and emissivity spectrum in the TIR spectral interval. ► Temperature and emissivity separation by a maximum entropy estimation procedure. ► The theory of MaxEnt estimation is discussed in detail together with a full description of the proposed algorithm. ► Application of the new TES algorithm to a representative test-bed is analysed and discussed by means of numerical simulations.
