Abstract：Under the influence of dispersive refraction and absorption of light caused by water medium, variation of illumination condition, and imaging distance, there are always some problems such as low contrast and serious blur devaluing the underwater image. Aiming at above problems, based on some researches which improving image quality, this paper chooses three different of underwater image datasets as targets and nine image quality improvement methods (which contains image enhancement and image restoration methods) to carry out the underwater comparative experiments, while analyzing the experimental results from six separate aspects such as time-consuming, peak signal to noise ratio, structural similarity measure, average gradient, entropy, and standard deviation. Experimental results shows that Histogram Equalization and Guided Filter performed the best according to the processed images, and achieved relatively satisfactory data results on the whole, which was believed to laid a basic foundation for further study.
