2D-Noise Generation Aided by Chaotic Map, Reversible Integer Wavelet Transform and Cellular Automata

摘要

This paper proposes an unique image encryption scheme in the hybrid domain based on Logistic Map, Reversible Integer Wavelet Transform, and Elementary Cellular Automata (CA). In the proposed work, position permutation is done using Logistic Map equation in the spatial domain and pixel value transformation is done using CA rule and randomly generated matrix created using Logistic map equation in the Transfer Domain with the help of Reversible Integer Wavelet Transform. This paper handouts a pristine application of Logistic map functions and CA in the transfer domain and in spatial domain. Analysis shows that the relationship among the transfer domain coefficients is greatly reduced and the randomness metric is equal to 7.999 much closer to the ideal value of 8.
