Image-registration

This is a z transform based watermarking algorithm used for copy right protection

此程序能将一个信号进行EMD分解，已近调试过，绝对没问题，主程序为emd1.m，用户可以随意更改里面的信号函数Xn。(This program converts a signal with EMD nearly debugged, absolutely no problem, main program for emd1.m, the user can freely change inside the signal function Xn.)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.
