本网站上下载的混沌加密的m代码，通过logistic映射生成了混沌序列并调制，实现了对水印信息的预处理。-The website of the chaotic encryption of m code, through the logistic chaotic sequence generated mapping and modulation to achieve a pre-processing of watermark information.

vs 2010编程验证Logistic映射的初值敏感性和对参数的敏感性，并用matlab编程作图实现-c++ programming, verification Logistic mapping initial sensitivity and sensitivity to parameter and plotted using matlab programming
