Adaptive Fusion Algorithm of Polarization Images in Visible Light

Whereas the recognition of target characteristics could be enhanced by the polarization image, polarization system of visible light and the dual-tree complex wavelet (DTCWT) fusion algorithm of polarization image had been presented in this paper. In the low-pass sub-band of Wavelet coefficients, the fuse rule based window energy had been adopted, while in the high-pass sub-band, the rule of spatial frequency self-adaption weighted at window had been selected. The setting of autocorrelation and the application of simulated annealing algorithm greatly improved the robustness and adaptability of fusion. Fused image with good subjective quality and objective evaluation of performance had greatly enhanced the target and background contrast.
