| Abstract: | The authors studied the feedback neural network applied to image reconstruction from a few projections.The quality of the reconstructed image was good,obtained by using Hopfield neural network,relating the energy function with the criteria of optimization used in judging reconstructed image,and using the Adaline model to adjust the weight of each criterion.The algorithm of image reconstruction based on the neural network is fast in convergence and high in precision,furthermore the quality of the image is satisfactory. |
