Gabor滤波器是一个用于边缘检测的线性滤波器。Gabor变换是一种短时傅里叶变换方法，其实质是在傅里叶变换中加入一个窗函数，通过窗函数来实现信号的时频分析。当选取高斯函数作为窗函数时，短时傅里叶变换称为Gabor变换。-Gabor filter is a linear filter for edge detection. Gabor transform is a short-time Fourier transform method, and its essence is to add a window function in the Fourier transform, to achieve through the window function frequency analysis. When you select a Gaussian function as a window function, short-time Fourier transform is called Gabor transform.
