The problem of embedding a binary image into another binary image is considered. We propose a method where the embedding is performed spatially, i.e., a smaller sized binary image (Image A) is embedded in a larger sized binary image (Image B). Image B is the only visible image when the composite is viewed directly. To view Image A, we can perform a suitable extraction operation on Image B. The embedding algorithm can be applied recursively so that the final binary image can contain a number of progressively smaller sized binary images. Examples are used to show the quality of the embedding. Admissible conditions and security issues of the embedding algorithm are considered.
