In the past few years, a number of image encryption algorithms based on chaotic maps have been proposed. One dimensional chaotic system with the advantages of high-level efficiency and simplicity, has ...

All tree leaves have an outer layer called the epidermis, which can also be used in the identification process. This leaf "skin" always has a waxy cover called the cuticle and varies in thickness ...

We develop and analyze methods for computing provably optimal maximum a posteriori probability (MAP) configurations for a subclass of Markov random fields defined on graphs with cycles. By decomposing ...
