We propose a novel image denoising strategy based on the correlation in the FREBAS transformed domain. FREAS transform is a kind of multi-resolution image analysis which consists of two different Fresnel transforms. It can decompose images into down-scaled images having the same size and having different frequency bandwidth. Since these decomposed images have similar distribution for the same direction from the center of FREBAS domain. Even the FEBAS signal is hidden in the noise in low SNR image cases, the signal distribution can be estimated using the distribution of the FREBAS signal located nearby the interested position. We develop an collaborative Wiener filter in the FREBAS transformed domain which implement the collaboration of standard deviaton of interested position and that of analogous positions. The experimental results demonstrate that the proposed algorithm improve the SNR in terms of both total SNR and SNR on the edge of images. |
