The PLAnt co-EXpression database (PLANEX) is a new internet-based database for plant gene analysis. PLANEX ( http://planex.plantbioinformatics.org ) contains publicly available GeneChip data obtained from the Gene Expression Omnibus (GEO) of the National Center for Biotechnology Information (NCBI). PLANEX is a genome-wide co-expression database, which(More)
In this paper, a novel application research on memristor is studied, and memristor-based chaotic circuit for text, image encryption and decryption is presented. In light of memristor characteristic, nonlinear circuit and chaotic cryptography, a new cryptosystem model of memristor-based chaotic circuit is designed. Then, text, image encryption and decryption(More)
Automatic facial expression recognition (FER) from non-frontal views is a challenging research topic which has recently started to attract the attention of the research community. Pose variations are difficult to tackle and many face analysis methods require the use of sophisticated normalization and initialization procedures. Thus head-pose invariant(More)
Two kinds of image encryption algorithms based on a three-dimensional chaotic system is presented in this paper. Firstly, a new three-dimensional chaotic circuit based on memristor is designed, and the characteristics of the chaotic system are studied. Secondly, we present two kinds of images encryption algorithms based on the chaotic sequences above, and(More)
