摘　　要：针对图像的传输中可能会产生噪声的影响和传输时间开销过大,导致图像的恢复效果较差的问题,基于数学中熵最大的原理,提出了一种基于熵函数的去噪重构算法。将该算法运用交替方向乘子法(alternating direction method of multipliers,ADMM)分而治之的思想提出了一种新的快速去噪算法。通过归一化均方误差(normalized mean square error,NMSE)和峰值信噪比(peak signal to noise ratio,PSNR)等评价标准进行实验仿真,验证所提算法的优越性。实验结果表明:根据上面思路提出的方法具有很好的效果,在去噪方面具有一定的用途。In order to solve the problem that there may be effects of factors such as noise and excessive transmission time overhead in the transmission of the image,which will result in poor image restoration effect,a denoising and reconstruction algorithm is proposed based on entropy function,which is based on the principle of maximum entropy in mathematics.A new fast denoising algorithm is proposed by using the idea of divide and conquer of alternating direction method of multipliers.The experimental simulation complying with normalized mean square error and peak signal to noise ratio evaluation criteria verifies the superiority of the proposed algorithm.The experimental results show that the proposed method has a good effect and has a certain use in denoising.
