In this paper, a new homomorphic image watermarking method implementing the Singular Value Decomposition (SVD) algorithm is presented. The idea of the proposed method is based on embedding the watermark with the SVD algorithm in the reflectance component after applying the homomorphic transform. The reflectance component contains most of the image features but with low energy, and hence waterma...
In the exploiting modification direction (EMD) method, a secret digit in (2n+1)-ary notational system is embedded into a group that is consisted of n pixels. Only one pixel in a group at most is being modified by either increasing or decreasing one. Therefore, the maximum embedding rate of EMD method is (log2(2n+1))/n when n≧2. In order to increase the embedding capacity of EMD method, a new ad...
Three methods of plastic embedding were assessed for their value in routine dermatopathology. The J B 4, Taab embedding, and Taab transmit techniques were compared for quality, convenience, and safety. The Taab transmit method was the most satisfactory method, being both rapid and simple. An additional advantage is that the resin can be removed and the immunoperoxidase technique carried out on ...
We apply the embedding method of Batalin-Tyutin for revealing noncommutative structures in the generalized Landau problem. Different types of noncommutativity follow from different gauge choices. This establishes a duality among the distinct algebras. An alternative approach is discussed which yields equivalent results as the embedding method. We also discuss the consequences in the Landau prob...
