一种水下图像增强算法的实现和仿真

〗由于水下环境的特殊性和复杂性,使得水下图像的质量差、图像对比度低。文中给出了一种基于空间域的图像增强方法,该算法利用均值算法估计水下图像背景,从原水下图像衰减背景图像,再对衰减背景之后的图像进行改进的图像锐化处理。通过对算法仿真结果的分析可知,处理后的图像整体对比度明显提升,同时使得目标的边缘更加清晰。

Realization and Simulation of an Underwater Image Enhancement Algorithm

The characteristic and complexity of the underwater environment makes the underwater image poor in quality and low in contrast.An image enhancement algorithm based on spatial domain is put forward in this paper.This algorithm utilizes the average algorithm to estimate the background image first,then subtracts the background image,and finally sharpens the image which has had its background subtracted.An analysis of the simulation result demonstrates that the contrast of images processed meliorates distinctly and the edge of the target is much clearer.
