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.   SEPARATING FIGURES, MATHEMATICAL FORMULAS AND JAPANESE TEXT FROM FREE HANDWRITING IN MIXED ONLINE DOCUMENTS 期刊论文  OAI收割 International Journal of Pattern Recognition and Artificial Intelligence, 2004, 卷号: 18, 期号: 7, 页码: 1173-1187 KEISUKE MOCHIDA; MASAKI NAKAGAWA   |  收藏  |  浏览/下载：18/0  |  提交时间：2010/05/13 Pen interfaces  online handwritten patterns  pattern segmentation  stroke classification  probabilistic model  segmentation by recognition  neural-network   Application of probabilistic neural network in the clinical diagnosis of cancers based on clinical chemistry data 期刊论文  OAI收割 analytica chimica acta, 2002, 卷号: 471, 期号: 1, 页码: 77-86 作者:  Shan, YC;  Zhao, RH;  Xu, GW;  Liebich, HM;  Zhang, YK 收藏  |  浏览/下载：246/106  |  提交时间：2010/11/30 classification  cancer  nucleosides  probabilistic neural network
