| 摘 要： | 针对噪声在多小波分解后的尺度性以及图像本身的特性,提出了一种基于遗传算法的多小波自适应去噪算法,该方法能通过遗传算法自适应地寻求去噪后图像的最小均方误差.实验结果表明,该算法优于传统算法,不仅能有效滤除图像的噪声,而且能较好地保留图像的边缘信息,具有更加理想的去噪效果.

| Abstract: | Aiming at the scaling of the noise after multiwavelet decomposition and the characteristic of image,a multiwavelet adaptive denoising method was proposed based on genetic algorithm.This method can adaptivly look for the least RMSE of the denoised image according to genetic algorithm.The experimental results show that this algorithm is superior to the traditional methods.It can not only remove the noise of image,but remain the better edge of image,and this method has more perfect denoising effects. |

| Keywords: | image denoising adaptive threshold genetic algorithm image characteristic |
