In t his paper , we segment t he sky area by bit2plane decomposition , and fit
circadian light scat tering using elliptical least squares , which could automatically determine t he cent ral
brightness of the sky. Then we weight t his cent ral brightness value wit h t he average bright ness value of the
segmented sky region as t he final sky region brightness. Finally , we use t he fog atmosp heric scattering model
to recover degraded images.
