abstraction

 [ab-strak´shun]
1. the mental process of forming ideas that are theoretical or representational rather than concrete.
2. the withdrawal of any ingredient from a compound.
3. malocclusion in which the occlusal plane is farther from the eye-ear plane, causing lengthening of the face.

(ab-strak'shŭn),
1. Distillation or separation of the volatile constituents of a substance.
See also: odontoptosis.
2. Exclusive mental concentration.

3. The making of an abstract from the crude drug.

4. Malocclusion in which the teeth or associated structures are lower than their normal occlusal plane.
See also: odontoptosis.
5. The processes or the results of discernment of formulation of general concepts from specific examples, and/or ascertainment of a given aspect of a concept from the whole.

All abstraction uses the concept of information hiding. When models are well designed, they are relatively independent.
Briefly speaking, topics in information hiding and multimedia signal processing are popular among academia, which is also much required for industrial applications.
(Some steganography tools have built-in intelligence to avoid the low-intensity portions of the signal.) Audio files are well suited to information hiding because they are usually relatively large, making it difficult to find small hidden items.
Both editors have a wealth of knowledge on information hiding as Katzenbeisser is a student of computer science at the Vienna University of Technology, while Petitcolas has received a Ph.D from the University of Cambridge and is currently employed by Microsoft Research Cambridge.
