Description: Gabor滤波器的原理是 其脉冲响应为一个谐波函数（即下式中的余弦函数）和一个高斯函数的乘积。根据信号与系统理论，时频域的卷积和乘积互为傅里叶变换。Gabor滤波器的傅里叶变换为谐波和高斯函数各自傅里叶变换的卷积-The principle of the Gabor filter is a harmonic of its impulse response function (i.e., the cosine function in the formula) and the product of a Gaussian function. According to the theory of signals and systems, time and frequency domain convolution product of the Fourier transform each other. Fourier transform of the Gabor filter and Gaussian function is the harmonic each convolution of the Fourier transform Platform: |

Description: 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. Platform: |
