JSteg
- JSteg隐写技术matlab实现代码--基本思想:用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位,但若量化后DCT系数为0或者1,则不进行处理。(DCT系数的LSB嵌入) -JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the leas

CST_airfoil_fitting
- 一个拟合CST曲线的程序,用来做翼型优化使用(也可以用到其它曲线拟合上)。 首先读入一个翼型数据,反求这个翼型的6*2个控制参数。通过这修改这个12个控制参数(其中的任意几个),来达到生成新的翼型的目的。(使用了NASA0714翼型作为例子 )-it is a code for airfoil curves fitting, which based on CST formula.Firstly, the program read a airfoil data,then the program
