Data hiding in stained glass images

Abstract

New methods for automatic generation of stained glass images as well as for data hiding in such images are proposed. Glass regions in stained glass images are generated by randomly sprinkled seeds and a region growing technique. The number of nodes of a tree constructed for pixel grouping in a glass region is used for data hiding in a stained glass image. A complete process for secret communication using the above technique is also proposed. Experimental results show the feasibility of the proposed methods.
