Goal¶ In this section, we will learn To find the Fourier Transform of images using OpenCV To utilize the FFT functions available in Numpy Some applications of Fourier Transform We will see following functions : cv2.dft(), cv2.idft() etc Theory¶ Fourier Transform is used to analyze the frequency characteristics of various filters. For images, 2D Discrete Fourier Transform (DFT) is used to find the
