blind source separation technique separates mixed signals blindly without any information on the mixing system. in this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. in these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. in order to evalu...
palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. texture is one of the most important features extracted from low resolution images. in this paper, a new local descriptor, local composition derivative pattern (lcdp) is proposed to extract smartly stronger...
The classic overall profit needs precise information of inputs, outputs, inputs and outputs price vectors. In real word, all data are not certain. Therefore, in this case, stochastic and fuzzy methods use for measuring overall profit efficiency. These methods require more information about the data such as probability distribution function or data membership function, which in some cases may no...
Introduction: A study on the presentation of a modified beta function formula to predict maxillary arch form in patients with cleft palate (CLP) is of great importance. In order to have this information, this study was done to present a modified beta function formula for predicting upper dental arch of patients with cleft lip and palate (CLP) and to assess its accuracy. Since this information c...
Abstract Chaotic systems are characterized by unidirectional, diffusive and initial value sensitivity of hash. Academia can use it to optimize algorithms for mathematical computer encryption keys. This paper focuses on a hash function mixed chaotic system with key. Then the state mapping relationship modified, conclusions obtained. optimal design messy technology key is introduced briefly. A dy...
