LOW-RANK PATCH-BASED BLOCK HANKEL STRUCTURED MATRIX FOR IMAGE INPAINTING

摘要

The present invention relates to a method for restoring a damaged image based on an extinction filter existing in a patch which means a localized area of the image, which restores damaged information of the image by using a matrix completion problem caused by performing matrix completion in the extinction filter. The extinction filter has a convolution relation with data of an image domain, and forms a rank lack block Hankel matrix formed through a commutative law of the convolution to perform matrix completion.
