p156_DFT_FFT

维纳滤波程序，一种信号处理程序，可用于数据预处理(Wiener filtering process, a signal processing procedure can be used for data preprocessing)

在matlab环境下利用LSB最低有效位算法将一个图片水印隐藏在载体图片中，并对被隐藏那个信息进行提取。(Matlab environment in the use of least significant bit LSB algorithm will be a picture watermark hidden in the picture carrier, and that information has been extracted hidden.)

It will perform the Zooming operation on input image.

Runge Kutta 4th order

This code calculates dimensionless pressure, and load carrying capacity for a finite width slider step bearing

这是基于小波变换的数字水印代码，在嵌入的水印加上一个pn尾随机序列(This is based on the wavelet transform digital watermark code, the embedded watermark with a random sequence late pn)
