hi am hayder i would like to get details on matlab code for chaotic image encryption ..My friend Justin said matlab code for chaotic image encryption will be available here and now i am living at baghdad and i last studied in the college mustinsiriah and now i need help on , the code of program used to implement 4d chaotic system to encrypt the color image .
thank you

A New Chaotic Algorithm for Image Encryption
Aim:
A new image encryption algorithm is presented based on Henon chaotic maps in order to meet the requirements of the secure image transfer.
Present Theory:
Technique for securing digital data is cryptography. Cryptography scrambles the message through an encryption process . DES is one of the cryptography algorithm. DES use ....etc

We present a method to compute the delay-constrained multicast routing tree by employing chaotic neural networks. The experimental result shows that the noisy chaotic neural network (NCNN) provides an optimal solution more often compared to the transiently chaotic neural network (TCNN) and the Hopfield neural network (HNN). Furthermore, compared with the bounded shortest multicast algorithm (BSMA), the NCNN is able to find multicast trees with lower cost. ....etc
