对偶梯度法在图像去噪中的应用

Application of a Fast Dual Gradient Method in Image Denoising

应用了一种加速的对偶梯度法,在原有的算法中加入了一步迭代算法,并对其做了数值仿真和实验,结果显示:该方法比原有的对偶梯度法能达到更好的图像去噪效果。

An accelerated dual gradient method is used to add a one-step iterative algorithm to the original algorithm,and numerical simulations and experiments are performed on it.The results show that the method can achieve better images than the original dual gradient method.
