Image Self-embedding with Large-area Restoration Capability

A method of self-embedding capable of restoring large-area contents is proposed in this paper. We present table for encoding the DCT coefficients that would help compressing each block to a fixed length of 32 bits. Two schemes are designed to improve the restoration ability. In the first scheme, we embed the information of two remote blocks into the least significant bits (LSB) of the current block. In the second scheme, two LSBs are used for embedding information as well as the authentication bits. Both schemes have the ability of large-area restoration, 66.7% and 75% on the upper bound respectively.
