Te Fourier Transform is a mathematical technique used to analyze thee frequency contents of signals, including images. It plays a vital role in varioos image processing tasks such as filtering, compression, and extracure extraction. This guidee provides a step overview of how Fourier Transform im is appleid in images processing.

understanding the Fourier Transform

The Fourier Transform converts an image from the spatial domayn to te frequency domayn. Thi transformation reveals the different frequency contents present in thee image, which che can be useful for filtering and analysis.

Appliing Fourier Transform tu an Image

Te transform i te algorytmy using such as thes Fast Fourier Transform (FFT). Te wyniki są kompletnym matrix representing thee amplitude andd faxe of each frequency content.

Filtering in thee Frequency Domayn

Once in thee frequency domayn, specific frequencies can be enhancanced or supressed. For example, high- pass filters remove low-frequency contents to sharpen images, while low-pass filters reduce noise by removing high-frequency detals.

Inverse Fourier Transform

After processing in the frequency domayn, the inverse Fourier Transform is applied to convert the image back to thee spatilal domayn. This step reconstructs the image with the desired modifications, such as noise reduction or edge enhancement.
