Neste artigo é proposto um método de restauração de imagens utilizando o filtro de Wiener. A fim de tornar a teoria do filtro de Wiener consistente com imagens que possuem estatísticas espacialmente variadas, o método proposto adota o filtro de Wiener localmente adaptativo (AWF) baseado no modelo universal de distribuição de mistura gaussiana (UNI-GMM) previamente proposto para remoção de ruído. Aplicando o UNI-GMM-AWF para problema de deconvolução, o método proposto emprega o filtro Wiener estacionário (SWF) como pré-filtro. O SWF no domínio da transformada discreta de cosseno reduz a função de propagação do ponto de desfoque e facilita a modelagem e filtragem no AWF seguinte. O SWF e o UNI-GMM são aprendidos usando um conjunto genérico de imagens de treinamento e o método proposto é ajustado ao conjunto de imagens. Resultados de simulação são apresentados para demonstrar a eficácia do método proposto.

Abstract: In this paper, an image restoration method using the Wiener filter is proposed. In order to bring the theory of the Wiener filter consistent with images that have spatially varying statistics, the proposed method adopts the locally adaptive Wiener filter (AWF) based on the universal Gaussian mixture distribution model (UNI-GMM) previously proposed for denoising. Applying the UNI-GMM-AWF for deconvolution problem, the proposed method employs the stationary Wiener filter (SWF) as a pre-filter. The SWF in the discrete cosine transform domain shrinks the blur point spread function and facilitates the modeling and filtering at the proceeding AWF. The SWF and UNI-GMM are learned using a generic training image set and the proposed method is tuned toward the image set. Simulation results are presented to demonstrate the effectiveness of the proposed method.
