- Abstract
- This paper proposes an image concealment technique based on block matching (BM) in IWT domain. The BM algorithm had the advantage of embedding the high capacity image, but it had the disadvantage that quality of the reconstructed secret image varies depending on the cover image. Therefore, this paper focuses on improving the quality of the reconstructed secret image while preserving the embedding capacity.
