High-frequency error concealment in wavelet-based image coding
Luigi Atzori, Daniele Giusto, A. Raccis · Electronics Letters · 2003
A new algorithm for high-frequency subband error concealment in wavelet-based picture coding is presented. It is based on a wavelet patch repetition approach: the LBG algorithm, given by Linde et al., is used to generate a codebook of patches and, according to a boundary distance measure, one of these patches is selected to mask the damaged area. Experiments show noteworthy results.
