| 摘 要： | 在图像盲复原中,NAS-RIF算法在无噪情况下,能够得到较好的复原结果,但是对有观测噪声的图像复原效果不理想。而Hopfield神经网络有利于缓解图像复原过程中的震铃效应,但前提是知道退化图像的点扩展函数。将二者相结合提出一种基于NAS-RIF算法和神经网络的图像盲复原新算法,首先由NAS-RIF算法先估计出退化图像的点扩展函数,再利用Hopfield神经网络算法对其进行复原。实验结果表明,该算法具有较好的盲复原效果。

| Abstract: | In blind image restoration,the NAS-RIF algorithm can obtain the better restoration result while without noise.When observational noise exists,the restoration obtained by NAS-RIF algorithm isn't ideal.However,Hopfield neural network is good at alleviating ringing effect in the process of restoration.But the premise is that the PSF of the degraded image has been known.Gives a new blind image restoration algorithm which based on NAS-RIF algorithm and neural network.NAS-RIF algorithm estimates PSF from degraded image at first,and then neural network restores.The result of the experiment shows that this algorithm will produce better effect than others. |
