This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was then started with different initial values, which were converted to three series of numbers from...

In 1988, the International Organization for Standardization (ISO) established the Moving Pictures Experts Group (MPEG) with the mission to develop standards for the coded representation of moving pictures and associated audio for digital storage media. The work of the MPEG group led to the development of several ISO standards, including ISO 11172, known as MPEG-1 [1]; ISO 13818, known as MPEG-2...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...
