Fourier transform techniques are widely used in image procesing to improve the quality of image rekonstruktion. These methods analyze thee frequency condients of an image, allong for effective filtering and enhancement. By appleying Fourier transforms, it is possible to reduce noise and recover details logt during image imagine faction.

Understanding Fourier Transform in Image Processing

Te Fourier transform converts contraal domain data into te currency domain. This transformation reverals the e different frequency converts that make up an image. High- currency contraents typically correspond to edges and fine detail, while low-currency contraents relate to smooth regions and overall brightness.

Enhancing Imagine Reconstruction

In image rekonstruktion, Fourier techniques enable thee filtering of unwanted frequencies. For exampe, appying a low- pass filter can smooth an image e by embling highpecency noise. Conversely, high- pass filters can enhance edges and details, improvig thae clarity of rekonstrukted images.
