- 傅立叶频谱图 应用离散傅立叶变换把一张图像从时域转换到频域-Fourier spectrum of discrete Fourier transform applied to an image from the time domain into the frequency domain
DFT2D
- 采用OPENCV封装的图像二维DFT运算，通过该类可生成图像二维傅里叶变换矩阵，通过可选参数可调整生成傅里叶矩阵、傅里叶频谱同时可选择对数加强属性增强傅里叶频谱的显示效果。-OPENCV package using two-dimensional DFT computation of image, the image can be generated through such two-dimensional Fourier transform matrix generated by the op

- 一种基于opencv的特殊fit变换法，输出图片的频谱-A transformation method based on a special fit opencv, the output spectrum of the picture
opencv-fft2
- 灰度图像的二维傅里叶变换(cv_gray_fft2)，二维傅里叶变换结果的幅值计算(cv_abs)，频谱平移(cv_gray_fft2shift)，将数值归一化到0到255区间(cv_range_0to255)是非常常用的四个功能！所以写成四个函数，方便将来调用！附运行截图~并附对应的MATLAB程序！-Dimensional Fourier transform of the grayscale image (cv_gray fft2), two-dimensional Fourier tran
