| contents | Image denoising stands as a critical challenge in image processing and computer vision, aiming to restore the original image from noise-affected versions caused by various intrinsic and extrinsic factors. This process is essential for applications that rely on the high quality and clarity of visual information, such as image restoration, visual tracking, and image registration, where the original content is vital for performance. Despite the development of numerous denoising algorithms, effectively suppressing noise, particularly under poor capture conditions with high noise levels, remains a challenge. Image denoising's practical importance spans multiple domains, notably medical imaging for enhanced diagnostic precision, as well as surveillance and satellite imagery where it improves image quality and usability. Techniques like the Fourier transform, which excels in noise reduction and edge preservation, along with phase congruency-based methods, offer promising results for enhancing noisy and low-contrast images common in modern imaging scenarios. |
