Description: 对Gabor时频变换在模态参数辨识中的应用进行了探讨,将基于Gabor系数展开的时频滤波方法作为参数辨识的前处理手段之一,该方法对于平稳、非平稳信号都适用。根据信号在时频域内的分布特征,可以直接观测系统的频率分布情况、模态密集程度、能量聚集性、各通道响应信号所含特征量的多少等信息,从而对响应信号的特征构成进行初步判断,并通过剔除、截取等操作实现对响应信号的滤波,更有利于模态参数的辨识。

Description: 这是一个时频分析中关于gabor变换的程序，此程序分离频率的效果不错。
Gabor变换：
式中a，b为常数，a代表栅格的时间长度，b代表栅格的频率长度
式中的 是一维信号x(t)的展开系数，h(t)是一母函数，展开
基函数是h(t)由作移位和调制生成的，
- This in a time frequency analysis about the gabor
transformation procedure, this procedure separation frequency effect
is good. Gabor transformation: In the formula a, b is the constant, a
represents the grid the time length, b on behalf of the grid frequency
length in the formula is the unidimensional signal x (t) launches the
coefficient, h (t) is a female function, launches the primary function
is h (t) by makes shifting and the modulation production,

Description: 基于opencv1.0实现的二维Gabor滤波器， Gabor变换属于加窗傅立叶变换，Gabor函数可以在频域不同尺度、不同方向上提取相关的特征。另外Gabor函数与人眼的生物作用相仿，所以经常用作纹理识别上，并取得了较好的效果。-Based on two-dimensional Gabor filter realization opencv1.0, Gabor transform is windowed Fourier transform, Gabor functions in the frequency domain of different scales, different direction extract relevant features. Gabor function and other biological effects similar to the human eye, so often used as a texture on the identification and achieved good results.
