用改进的周期图（Bartlett）法求1KHz方波信号加高斯白噪声的功率谱密度(Use the Bartlett to compute the power spectral density)

说明：  matlab程序，高阶谱分析，信号谱分析的方法一起就存在了，高价谱分析是当代信号处理的主要工具。-(Matlab procedures, higher order spectral analysis, signal spectral analysis method in existence, high spectral analysis of contemporary signal processing major tools. )

这是编好的程序[cp,zq]=grnn(data,yy) gaussian SVM，GRNN 的正确率，击中率，正确拒绝率在19个先天盲人中的为： SVM GRNN 0.68421 0.73684 0.83333 0.83333 0.42857 0.57143 解压到MATLAB的TOOLBOX文件夹里，然后刷新工具箱，在命令窗口输入：rehash toolboxcache。 然后就可以用我的那个函数了。( It is programmed procedures [cp, zq] = grnn (data, yy) gaussian SVM, GRNN accuracy rate, hit rate and correct rejection rate in the 19 congenital blind as follows: SVM GRNN 0.68421 0.73684 0.83333 0.83333 0.42857 0.57143)

In this paper, a multimodal image fusion algorithm based on multiresolution transform and particle swarm optimization (PSO) is proposed. Firstly, the source images are decomposed into low-frequency coefficients and high-frequency coefficients by the dual-tree complex wavelet transform (DTCWT). Then, the high-frequency coefficients are fused by the maximum selection fusion rule. The low-frequency coefficients are fused by weighted average method based on regions, and the weights are estimated by the PSO to gain optimal fused images. Finally, the fused image is reconstructed by the inverse DTCWT. The experiments demonstrate that the proposed image fusion method can illustrate better performance than the methods based on the DTCWT, the support value transform (SVT), and the nonsubsampled contourlet transform (NSCT).
