Classical approaches to this problem involve complex iterative minimization procedures  typically with high computational costs. In this paper is proposed a novel algorithm for super-resolution that enables a substantial decrease in computer load. First  decompose and reconstruct the image by wavelet packet. Before constructing the image  use neural network in place of other rebuilding method to reconstruct the coefficients in the wavelet packet domain. Second  probabilistic neural network architecture is used to perform a scattered-point interpolation of the image sequence data in the wavelet packet domain. The network kernel function is optimally determined for this problem by a MLP-PNN (Multi Layer Perceptron - Probabilistic Neural Network) trained on synthetic data. Network parameters dependent on the sequence noise level. This super-sampled image is spatially Altered to correct finite pixel size effects  to yield the final high-resolution estimate. This method can decrease the calculation cost and get perfect PSNR. Results are presented  showing the quality of the proposed method. 2008 IEEE.   A case study of ecological restoration at the Xiaoyi Bauxite Mine, Shanxi Province, China 会议论文 International Conference on Ecological Engineering (ICEE 96), BEIJING, PEOPLES R CHINA, OCT 07-11, 1996 作者:  Gao, L;  Miao, ZW;  Bai, ZK;  Zhou, XY;  Zhao, JK 收藏  |  浏览/下载：14/0  |  提交时间：2016/01/19 ecological restoration  open-pit mine  mineland restoration
