METHOD AND DEVICE FOR RECONSTRUCTING A SELF-SIMILAR TEXTURED REGION OF AN IMAGE

摘要

The invention proposes a method for reconstructing a self-similar textured region of an image. Said method comprises determining pixels of a part of the self-similar textured region by copying sample pixels from a sample part of the self-similar textured region, the sample pixels being selected using a neighbourhood matching, wherein a size of neighbourhoods used for matching is selected based on an analysis of descriptors computed from coefficients of DCT transform of differently sized blocks of the sample part. The analysis of descriptors computed from coefficients of DCT transform of differently sized blocks of the sample part allows for determining the neighbourhood size close to a feature size of the texture.
