代码说明:

应用背景通过载体对信息进行隐藏,保证在不影响载体视觉效果的前提下实现信息隐藏;关键技术通过离散余弦变换(DCT)将需要隐藏的信息嵌入到载体中从而达到信息隐藏的目的。

    说明:  中文的基于matlab得直升机模拟,做的还行,就是有点假,实现没有只有他自己知道。(A helicopter flight control system simulation software package was introduced, which was developed on MATLAB 6.5. Several unit math models and system simulation were introduced. The software has made good effect on designing one helicopter flight control system. It is helpful for designing and velidating the control law of helicopter.)

  • 图像融合
    用matlab将一张图像感兴趣的某些范围,无缝的融入另一张图像中。使融入的图像没有明显的分割线处理整幅灰度图像的全局 Poisson 方法对前背景之间比较平滑的情况有很好的处理效果,F-B 的值在计算不透明度的梯度时有至关重要的作用,如果 F 和 B 的值差别较小,即图像前背景比较接近,则不透明度的梯度变化率会很大,也就是说α 的分布会很不平滑。

    This is a compilation of programming hints and examples about how to use and program MAT- LAB, with a mind on numerical methods. At present time, this is work in progress, so it s important to know which version of this document you are dealing with. There will not be detailed explanations of the examples: I will specically concentrate on where I think you might have trouble or you might be learning something new.
