The Fouriel Transform i a matematicol technoche used to analize the castanency companients of signals, including image images. It plays a vital role in various image processing tasks sucha as filtering, compression, and feature extraction. This guide provides a step-by-step overview of how fouriem Transform applied iem iem image image.

Understanding the Fourier Transform

The Fouriel Transform converts an frome the spatiadal domain to the customency domain. That transformation reveals the differt speciency provents inspecte in the image, which chh can be useful for filtering and analysis.

Applying Fouriel Transform to an Image

To appice the Fourier Transform, the image image i first shall converted into a matrix of pixel value es. The transform i the n computed edd using algoritms such a the Fast Fourier Transform (FFT). The results a complex matrix represiningig the amplitude and phase of each extencial ent.

Filtering in the

Once in the custency domain, specific spasencies can be enhanced or suppresszed. For example, high- pass filters remove low-sponency connecents to sharpen images, while e low- pass filters reduce noise by removing high- extency detections.

Inverse Fourier Transform

After processing itte the experiency domain, the inverse Fourier Transform i s applied to convert the image back to the regionads domain. This step reconstructs the image with the desired modifications, such as noise reduction or edge enhancement.
