A multi-scale modeling method for thermal-degraded image

This paper proposes a multi-scale modeling method for thermal-degraded image. The method adopts the least-squares fitting method to model the thermal degradation characteristics of simulation degraded images at multi-scale, and then uses the obtained modeling results to correct the degraded images in real aerodynamic thermal environment. The experimental results show that this method is effective in thermal-degraded image correction, and improves the image quality.
