New method of multiple image restoration based on orthogonal polarization direction
According to the principle of polarization effect in the process of atmospheric scene imaging
the polarization imaging equation is established
and a new image restoration method based on the two polarization directions is proposed. A new polarization image restoration equation is derived by combining the atmospheric scattering physical model based on the principle of multiple polarization image restoration. First
the method uses bilateral filtering to estimate the atmospheric veil by the polarization image
and adaptively adjust it according to the image evaluation index. Finally
we restore the original clear image of polarization image combining the image matching and fusion restoration equation and select the appropriate parameter adjustment method to solve the large sky area containing the halo effect caused by haze image restoration. The experimental results by the polarization images obtained by the sensor and the KENKO CPL67MM polarizing filter were compared with those of the representative single image restoration methods. The results show that the algorithm can effectively recover the fog image and automatically adjust the parameters because the restoration information is more abundant.
