代码说明:

  图像进行小波分解后,对于相对来说不重要的高频成份采用较高的阈值,进行高压缩;而对集中图像大部分能量的低频成分采用较小阈值,以确保图像恢复时的质量(Image Compression)

  • ode45-matlab
    本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多,且程序充分展示了Matlab向量运算的强大功能,以及编程的简单快捷。(This procedure is particularly suitable for use ballistic calculations and other aspects. ODE45 faster than a lot of functions and procedures for demonstrating the power of Matlab vector operations, and programming simple and quick.)
