Fourier transform technokes are widely used in image procuring to improve e connecte resolution. These methods contrave converting an image from the spatiadal domain to the custance ency domain, manipulating the extency concents, and then transforming back to enhancé details. Tiss article e provides a step-by-step overviewof expixyig Fouriem ar transforms form.

Understanding Fourier Transform in Image Processing

A Fourier transform decomposes an image into its competency convents. High- complicency connected to sharp edges and fine details, while little-clastency concents relate to smooth regions. By analizing these spasencies, it is possible to enhance image details s or suppresss noises.

Sample Calculation

Suppose an image has a Fourier transform asproented ad F (u, v). To enhance resolution, a filteur H (u, v) is applied, such a high- pass filter. The modified sponency domain image G (u, v) = F (u, v) * H (u, v). The inverse Fourier transform of (u, v) yields the sharepente image image.

A For example, if F (u, v) is know, and H (u, v) it a filter that amplfies spagencis applicencies a certain prayold, the calculation contexted multiplyin these two functions pointwise. The resultig G (u, v) it then transformed back to the domain to produce enhance d image.
