A Collaborative Adaptive Wiener Filter For Image Restoration Using A Spatial-Domain Multi-Patch Correlation Model, Khaled M. Mohamed, Russell C. Hardie
A Collaborative Adaptive Wiener Filter For Image Restoration Using A Spatial-Domain Multi-Patch Correlation Model, Khaled M. Mohamed, Russell C. Hardie
Russell C. Hardie
We present a new patch-based image restoration algorithm using an adaptive Wiener filter (AWF) with a novel spatial-domain multi-patch correlation model. The new filter structure is referred to as a collaborative adaptive Wiener filter (CAWF). The CAWF employs a finite size moving window. At each position, the current observation window represents the reference patch. We identify the most similar patches in the image within a given search window about the reference patch. A single-stage weighted sum of all of the pixels in the similar patches is used to estimate the center pixel in the reference patch. The weights are based …
