Descr iption: Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thu

频率域熵图，两个窗口，熵的径向和角向分布，便于分析纹理，还有一个自己写的gabor变换，请参考。-Frequency domain entropy map, two windows, the entropy of the radial and angular distribution, to facilitate analysis of texture, there is a transform gabor wrote it myself, please refer to.

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 fr

傅里叶变换是一种信号处理中的有力工具，可以帮助我们将图像从空域转换到频域，并提取到空域上不易提取的特征。但是经过傅里叶变换后，图像在不同位置的频度特征往往混合在一起，但是Gabor滤波器却可以抽取空间局部频度特征，是一种有效的纹理检测工具(Fu Liye transform is a powerful tool in signal processing, which helps us transform images from airspace to frequency domain and e
