A ROI-based self-embedding method with high recovery capability

Hongliang Cai, Huajian Liu, Martin Steinebach, Xiaojing Wang

ICASSP 2015accepted

In this paper, a novel block-wise fragile image watermarking algorithm for tampering localization and recovery is proposed. The image is divided into Region of Interest (ROI) and Region of Non Interest (RONI). Considering the ROI-based self-embedding problem as a special erasure channel, fountain co…

A novel image secret sharing scheme with meaningful shares

Hongliang Cai, Huajian Liu, Qizhao Yuan, Martin Steinebach, Xiaojing Wang

ICASSP 2015accepted

In this paper a novel (t, n) threshold image secret sharing scheme is proposed. Based on the idea that there is close connection between secret sharing and coding theory, coding method on GF(2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> ) is…
