A polarization image false color fusion method for target against dark background

To overcome the draw back of traditional false color fusion methods for polarization images , a new false color fusion method is proposed in this paper.Firstly, all of the polarization parameter images are obtained by polarization information analysis.Then the robustness of the obtained polarization information is estimated by the spatial distribution characteristics of the polarization angle. Finally, an alternate mapping for the strong polarization characteristic region ( the target region) and the noise region (the background region) is accomplished.The experimental results show that the proposed method has good quality and is easy to be further segmented and identified.
