一些关于IIR数字滤波器的设计理论，还有Matlab源程序，供设计数字滤波器人员参考(Some information about IIR digital filter design theory, as well as Matlab source code for the design of digital filters for reference staff)

A method to deduce band structure

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
