main

A fourier filter for time-series signals. Does not require the Signal Processing Toolbox. There is an interactive version with sliders that allow you to adjust the filter parameters continuously while observing the effect on your signal dynamically.

this code implements a new watermarking method

非静止多波束声呐混响的自回归模型。综合考虑了环境，几何结构等多种因素通过时变自相关函数仿真混响复数据序列。(This work describes a technique for simulating nonsta- tiouary multibeam Gaussian sonar reverberation sequences. The primary objective is to simulate quadrature-demodulated complex digital vector sequences that have a prescribed time-variaut Covariance function. )

本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力(failed to translate)
