After an image is transformed and described as a series of spatial frequencies, a variety of filtering algorithms can then be easily computed and applied, followed by retransformation of the filtered image back to the spatial domain. Interactive Tutorials Fourier Transform Filtering Techniquesįourier transformation belongs to a class of digital image processing algorithms that can be utilized to transform a digital image into the frequency domain.
