理论力学问题——大角度单摆的MATLAB模拟(Theory of mechanical problems- MATLAB simulation of large-angle pendulum)

It consists of 2 images input and watermark image.The aim of the program is th hide watermark image within input image.The last 4 digits of the input image are replaced by first 4 bits of the input image.The output image appears like input image but watermark image will be embedded inside.

This is a Random Sequence generator used in Cryptography, Spread Spectrum, Information Security
