Data hiding error concealment for JPEG2000 images

摘要

This paper presents an error concealment technique for image transmission in JPEG2000 for the lowest frequency coefficients. The proposed method uses the layer structure that is a feature of the JPEG2000. The most significant layer is hidden in place of the lowest layer of the bit stream. After transmission this embedded layer is used for error concealment. The bit stream encoded using the proposed method has the same data structure as the standard JPEG2000. Experiments show the effectiveness of these algorithms.
