Abstract: For promoting the development of underwater image subsequent processing technology and overcoming the shortage of traditional polarization image fusion method, this paper proposes a method of underwater polarization image fusion base on wavelet transforms and color transfer. Firstly, extracts the polarization parameters images, degree of polarization and angle of polarization image, in the wavelet domain removes redundancy and fusion exploiting the complementary and redundancy between them, then transmitts the color information of synthetic approximation unpolarized image to the fusion image. The experimental results show that this algorithm not only has good color expression, but also can improve the target detection and recognition.

Key words: underwater polarization image, wavelet transforms, color transfer, image fusion
