Seawater, as a typical scattering media, makes the high-resolution underwater vision technique influenced by the degradation of underwater imaging. Image degradation results from attenuation and scattering caused by environmental media. Forward scattering causes the slight blur of image details, while backscattering causes serious image spray. In order to improve the quality of underwater image, this paper does the research on color image enhancement in underwater environment.This paper introduces the optic...
