Paper Abstract

In this paper, we propose a new adaptive embedding technique which decomposes the image into various bitplanes based on redundant number systems. This technique is driven by three separate functions: 1) Adaptive selection of locations and number of bits per pixel to embed. 2) Adaptive selection of bit-plane decomposition for the cover image. 3) Adaptive selection of manner in which the information is inserted. Through the application of sensitive directional-based statistical estimation and a recorded account of actions taken, the proposed algorithms are able to provide the desired level of security, both visually and statistically. In comparison with other methods offering the same level of security, the new technique is able to offer a greater embedding capacity.
