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(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 )

地震波阻抗反演，用于一维、二维褶积模型，其中梯度函数和目标函数根据自己的需要建立(Seismic impedance inversion, for one-dimensional, two-dimensional convolution model, in which the objective function and the gradient function according to their own needs to establish)

tps模拟退火 cost存放了一个强连通图的边权矩阵，作为一个实例。 可在workspace中加载 运用此算法要注意多次试验。(tps simulated annealing cost holds the edge of a strongly connected graph weight matrix, as an example. Loaded in the workspace using this method should pay attention to several experiments.)

this is program is used to convert any kind of colour image to grey scale image. when this code is executed , an window is displayed to accept image and output image is created in the same folder
