全局最优粒子群优化算法，基本粒子群优化算法。(Global optimization PSO, Particle Swarm Optimization Algorithm.)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

bpmpd是用fortran77语言编写的一个state-of-the-art求解大规模线性规划程序，使用不可行原-对偶内点法（infeasible primal-dual interior point method）求解(bpmpd is a FORTRAN77 language state-of-the-art for solving large-scale linear programming procedure, the original use is not feasible- dual interior point method (infeasible primal-dual interior point method) for solving)

基于FFT谱连续细化算法的高精度频率估计，这种算法可以精确到小数点后两位，这种算法与MUSIC法和ESPRIT法相比，计算量大大降低，而且精度非常高。(This procedure is based on the FFT spectrum continual refinement algorithm s high accuracy frequency， this algorithm may precisely to decimal point latter two, compared the MUSIC algorithm and the ESPRIT algorithm, the computation complexity reduces greatly, moreover the precision is high.)

matlab图像水印嵌入处理，运用DCT算法进行嵌入和提取。(Matlab watermark embedding process, using DCT algorithm to embed and extract. )

Forensic science it the study of objects that relate to a crime. Forensic scientists study evidence so that it can be used in a court of law. Forensic scientists observe, classify, compare, use numbers, measure, predict, interpret data, and draw inferences based on evidence. In this lesson, students will use these science inquiry skills.In this dental image was classify by sift algorithm
