Abstract
|
|
This project objective is to implement a simple, easy-to-use ImageJ
plug-in for fast denoising of noisy images using a blind Wiener Filter. The
noise is a white Gaussian noise, and the noisy image’s Power Spectral Density
follows :

Image Goldhill
|
Noisy Goldhill, SNR 15
|
|
Projected Gradient denoised, SNR 21.24
|
Projected Newton denoised, SNR 21.27
