Image scrambling is an important technique in digital image encryption and digital image watermarking. This paper presents a novel image scrambling method using Poker shuffle, which is controlled dynamically by chaotic system. Compared with other scrambling techniques such as algebraic permutations and chaotic permutations, the proposed method has properties of nonlinearity, non-analytic formula and...
The performance and capacity of chaos communication systems are degraded in the presence of narrowband interference. The minimum phase space volume (MPSV) method is a well known method to suppress narrowband interference in chaos communication, however, its computing burden is heavy in estimating model parameters due to random search, and the AR model stable assumption does not usually satisfied....
