摘要 因水下信道的特殊性以及成像的复杂性,使得水下图像中的不确定因素给图像处理带来严重的影响。本文主要介绍了一种利用小波变换进行水下图像增强的方法。为降低对水下图像噪声增强程度,方法对不同尺度上的系数进行不同尺度的对比度增强。通过真实水下图像实验证明了该方法的有效性。 Because of the speciality of the underwater channel and the complexity of imaging environment, the uncertain factors in underwater image priduce serious impact on image processing.The arcticle pfincically proposed an underwater images contrast enhancement method .of wavelet teransform. The decomposed coefficients at different scales are enhanced in different degrees so as to decrease the degree of enhancement of noise in underwater images.Experimental results analysis proved the effectiveness of the method proposed .
