| 摘 要： | 由于退化图像的点扩散函数难以准确确定,提出一种基于Fourier正交基函数的前向神经网络图像复原模型,该模型以一组Fourier正交基为隐层神经元的激励函数,根据误差传递算法进行权值修正,达到收敛目标。给出Fourier神经网络及其相应的衍生算法的图像恢复实现步骤。实验表明,该方法能较好地实现图像的复原。

| Abstract: | According to the fact that PSF(point spread function) of the degraded image can’t obtain accurately,this paper constructed a feed-forward neural network for image restoration based on the Fourier orthogonal function.The hidden-layer neurons were activated by a series of Fourier orthogonal functions,updated its weight by the error back-propagation training algorithm and finally reached convergence target.This paper applied the Fourier neural network and its hidden-neuron growing algorithm to recover the fuzzy image.Experiments show they have better performances on image restoration. |
