pixels. In other words, minor changes in regular areas are more dramatic than larger modifications in edge ones.
Our first proposal is thus to embed message bits into edge shapes while preserving other smooth regions.

the edge regions are.
Then the data hiding algorithm is achieved by applying LSBMR on pixels of these regions.
