Edges form the outline of an object: they are the boundary between overlapping objects or between an object and the background. A small modification of pixel value in the stego image should not be harmful to the image quality: in cover image, edge pixels already break its continuity and thus already contains large variation with neighbouring -pixels.

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