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)

基于windows的任务管理器开发设计 windows task mananger(Based on the windows task manager development and design windows task mananger)

本程序是用于处理端点效应时的信号延拓方法，次程序是用于前段延拓，对于后端延拓的话直接把原信号进行翻转后再进行延拓，延拓后将信号再翻转回来就行。(This program is a signal extension methods for processing when the end effect, sub-program for front extension, extension to the rear end, then flip directly to the original signal and then carry out extension, the extension will signal the extension then flipped back on the line.)
