Tenacious tagging of images via Mellin monomials
We describe a method for attaching persistent metadata to an image. The method can be interpreted as a template-based blind watermarking scheme, robust to common editing operations, namely: cropping, rotation, scaling, stretching, shearing, compression, printing, scanning, noise, and color removal. Robustness is achieved through the reciprocity of the embedding and detection invariants. The emb...
متن کاملTrends in prosthodontics.
Prosthodontics is concerned with the impact of tooth or tissue damage and partial or complete loss of teeth on oral function in its broadest sense. It deals with this largely through prosthetic replacement. The discipline occupies a major portion of a dental school curriculum, and dental practitioners usually devote much of their practice to prosthodontic services. With the rapid improvement in...
متن کاملGreen Quaternions, Tenacious Symmetry, and Octahedral Zome
We describe a new Zome-like system that exhibits octahedral rather than icosahedral symmetry, and illustrate its application to 3-dimensional projections of 4-dimensional regular polychora. Furthermore, we explain the existence of that system, as well as an infinite family of related systems, in terms of Hamilton’s quaternions and the binary icosahedral group. Finally, we describe a remarkably ...
متن کاملTenacious Domain Walls in Supersymmetric QCD
We study the structure of the tenacious (existing for all values of masses of the matter fields) BPS domain walls interpolating between different chirally asymmetric vacua in supersymmetric QCD in the limit of large masses. We show that the wall consists in this case of three layers: two outer layers form a “coat” with the characteristic size ∼ Λ SYM and there is also the core with width ∼ m−1....
متن کاملRemovable Prosthodontics Section Editors
T individuals rendered edentulous and provided with complete dentures display marked changes in jaw relations due to resorption of the residual alveolar ridges. The changes are characterized by an upward rotation of the mandible with a resulting decrease in occlusal vertical dimension and increase in mandibular prognathism. I-3 The most rapid changes occur during the first year, when the rate o...
