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.   Analysis of man-made target detection in SAR imagery 会议论文  OAI收割 Envisat Symposium 2007, Montreux, Switzerland, April 23, 2007 - April 27,2007 Wang, Changlin; Zhong, Xuelian 收藏  |  浏览/下载：23/0  |  提交时间：2014/12/07 Synthetic aperture radar  Algorithms  Automatic target recognition  Computation theory  Data processing  Image acquisition  Target tracking   Comparison of pixel-based fusion between multi-spectral data and high spatial resolution data 会议论文  OAI收割 Image Processing and Pattern Recognition in Remote Sensing II, Honolulu, HI, United states, November 8, 2004 - November 9,2004 Zhao, Shuhe; Wang, Ziyu; Dong, Xieqiong; Chen, Xiuwan 收藏  |  浏览/下载：23/0  |  提交时间：2014/12/07 Remote sensing  Image analysis  Maximum likelihood estimation  Principal component analysis  Sensor data fusion  Synthetic aperture radar  Wavelet transforms
