摘　　要：针对水下环境存在的颜色衰减和散射效应导致水下图像颜色严重失真的问题,提出伽马变换和Retinex相结合的彩色水下图像增强算法。选择伽马参数,对图像进行伽马矫正,然后利用单尺度Retinex进行增强。仿真实验表明,该算法在改善水下图像照度信息的同时,保留了饱和度和色度信息,解决了水下图像增强的颜色失真问题,使水下图像具有较高的对比度和清晰度。Aiming at the existing color attenuation and scattering effect of the underwater environment lead to serious distortion of underwater image color problems,combined with gamma transform and Retinex put colorful underwater image enhancement algorithm.Choose gamma parameters,gamma correction to the image,then uses single measure Retinex enhanced.Simulation experiments show that the algorithm in improving the underwater image illumination information at the same time,retain the saturation and hue,can solve the problem of color distortion of underwater image enhancement,the underwater image with high contrast and clarity.
