说明：  根据Gadner公式编制的密度拟合程序，适合地震解释中没有密度只有速度的情况下自动生成密度(Prepared according to the density of the formula Gadner fitting procedure for seismic interpretation in the case of no density is only under the automatic generation of speed-density)

图象处理基础算法原代码MATLAB 集合。(image processing algorithms based on the original MATLAB code set.)

对变速率的数字信号处理的仿真实验进行验证，进行相应的滤波器的设计，以减少变速率中的失真(Variable rate digital signal processing of the simulation experiment for authentication, corresponding to the filter design, in order to reduce the distortion in the variable-rate)

it s a software made of

此程序为matlab的关于空间增强的一段代码，已经用于开发的软件中(This process is enhanced matlab on a piece of code space has been used to develop the software)

Ali H. Sayed 2008编写的Adaptive filters是经典的介绍滤波器的书籍。 文件太大，只能分部分上传。 这是第四部分。(Ali H. Sayed 2008 Adaptive filters are written in classic books introduce filters. File is too large to upload only sub-section. This is the fourth part.)

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

This is the library svm.
