What is MATLAB FFT and IFFT Applications about?
This document discusses the use of discrete Fourier transforms and filters for image processing. It applies the FFT algorithm in MATLAB to signals and an image, separating the image into low and high frequency components using Butterworth filters. The low frequency part carries color/luminance data while the high frequency part carries texture data. Basic blurring and sharpening filters are also demonstrated by scaling the high frequency components before reconstructing the image via inverse FFT.
