FIND COUNTOUR WITH FAMOUS ALGORITHMS

说明：  运用粒子群算法优化支持向量机的参数，效果比较好(The use of particle swarm optimization algorithm for support vector machine parameters, the effect is better)

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 )

这里给出了几个可见光通信的MATLAB程序，调制方式采用OFDM调制解调，对于可见光通信的研究者具有重要的参考价值。(Here are a few visible light communication MATLAB program, modulation using OFDM modulation and demodulation for visible light communication researchers have important reference value.)

adaptive equalization for decision feedback equalizer

该程序用matlab写成，已包含vof（根据Hirt的方法）内容，但该部分尚不成熟。对于不包含自由面的计算比较成功。(The program written with matlab, included vof (according to Hirt' s method) content, but that part is not yet mature. For the calculation of the free surface does not contain more successful.)

dc motor model

导线网平差，主要是附和导线平差程序，用于计算各点坐标并评定其精度。(Wire network adjustment, mainly echoing the wire adjustment procedure used to calculate the coordinates of each point and to assess its accuracy.)
