Abstract :
A new method of image transmission and cryptography on the basis of Mobius transformation is proposed in this paper. Based on the Mobius transformation, the method of modulation and demodulation in Chen-Mobius communication system, which is quite different from the traditional one, is applied in the image transmission and cryptography. To make such a processing, the Chen-Mobius inverse transformed functions act as the “modulation” waveforms and the receiving end is coherently “demodulated” by the often-used digital waveforms. Simulation results are discussed in some detail. It shows that the new application has excellent performances that the digital image signals can be restored from intense noise and encrypted ones.
