MATLAB中单位脉冲信号和单位抽样序列的产生程序(MATLAB in the sampling unit and unit pulse sequence generation program)

an inferior assistant or a channel administrator hopes to append some additional message, such as the origin information, image notation or authentication data, within the encrypted image though he does not know the original image content. some parameters are embedded into a small number of encrypted pixels, and the of the other encrypted pixels are compressed to create a space for accommodating the additional data and the original data at the positions occupied by the parameters
