Error Concealment Using Layer Structure for JPEG2000 Images

概要
- 論文の詳細を見る
A method of error concealment for JPEG2000 images is proposed in this paper. The proposed method uses the layer structure that is a feature of the JPEG2000. The most significant layer is hidden in the lowest layer of the JPEG2000 bit stream, and this embedded layer is used for error concealment. The most significant layer is duplicated because JPEG2000 uses bit-plane coding. In this coding, when the upper layers are affected by errors, the coefficients of the lower layers become meaningless. A bit stream encoded using the proposed method has the same data structure as a standard JPEG2000. Therefore, it can be decoded by a standard decoder. Our simulation results demonstrated the effectiveness of the proposed method.
