Infrared image synthesis of background and target using temperature estimation

Abstract

This paper proposes a method for generating a three wavelength bands, LWIR (long wave IR), MWIR (middle wave IR), and SWIR (short wave IR) image by synthesizing background image and target image of an arbitrary infrared wavelength band. In the proposed method, temperature of each image is estimated from background image and target image of certain wavelength band, and then temperature image is generated by combining estimated temperature information of each image. Finally, synthesized temperature image is converted into radiance image of three wavelength bands.
