一个好的变分模态分解，开源码

说明：  计算梯度下降法计算极值，只能找到局部最小点。可以通过调整步长实现全局最小(Calculation of gradient descent method to calculate extreme value, can only find local minimum point. By adjusting the step size can achieve the global minimum)

窄带、宽带ARMA模型的N、p、信噪比等不同时对谱估计的分析(Narrowband, broadband ARMA model N, p, N, which are not at the same time spectral analysis)

室内无线定位技术，基于比例圆算法的matlab仿真程序(Indoor wireless positioning technology, based on proportional circle algorithm matlab simulation program)

基于matlab的关于遗传算法的一些重要的函数的m文件，供读者参考 (Based on some of the important matlab m file on genetic algorithm function for readers reference)

由于图像在经过一次 JPEG 压缩和双重 JPEG 压缩之后其 DCT 系数具有一定的相关性，通过对这种相关性进行分析，提出了一种基于 JPEG 图像双重压缩特性的图像篡改检测算法，并用此算法检测图像是否经过篡改和定位篡改区域。 (Since the image after a first JPEG compression JPEG compression and double its DCT coefficients having some relevance, by this correlation is analyzed, and an image based on JPEG image compression characteristic double tamper detection algorithm, and the algorithm used to detect whether the image been tampered with and locate the tampered areas.)
