Frequency Domain Analysis of Digital Images Using Fourier Transform
Fourier analysis provides a powerful framework for decomposing digital images into their constituent spatial frequency components. This technique enables precise manipulation and interpretation of image structure beyond what is visible in the pixel domain.
Core Concepts
The two-dimensional discrete Fourier transform (2D-DFT) maps an M × N grays ...
