Due to the influence of various meteorological factors such as fog and light in the sea area
the image obtained by the photoelectric equipment has different degree of degradation
which leads to the decrease of the display quality of the image. In order to improve the effectiveness of image enhancement method in marine environment
this paper analyzes four commonly used image enhancement algorithms
including image enhancement algorithm based on histogram equalization
the Fourier algorithm of the original color principle
the image enhancement algorithm based on Retinex
the image enhancement algorithm based on homomorphic filtering
and summarizes the characteristics and the use of these algorithms. The above four kinds of image enhancement algorithms are applied to the image enhancement in the sea area environment. Choosing the appropriate enhancement algorithm can effectively improve the image contrast and overcome the problem of sea fog and illumination unevenness.
