Abstract
A system and method whereby acoustic signals can be classified and identified as to nature and location of the original signal. The system and method determine from an arbitrary set of signals a signature or other characterizing feature and distinguish signals associated with a plurality of conditions by means of dictionaries comprising atoms of signals.
Claims19
An apparatus for extracting, detecting, classifying, discriminating, localizing, and processing acoustic signals comprising:
- a. at least one device capable of collecting a plurality of signals;
- b. an algorithm capable of producing a simultaneous sparse approximation of said signals;
- c. a computer memory capable of storing structure-book representations;
- d. an algorithm capable of operating on stored structure-books to produce new structure books,
1 more element
A method of signature extraction comprising the steps of:
- a. establishing two or more analysis sets, each set comprising at least one signal;
- b. producing one or more simultaneous sparse approximations of collection of signals;
- c. producing a parametric mean structure book representative of each group signature.
A method of signal detection and classification comprising the steps of:
- a. collecting at least one signal;
- b. producing one or more simultaneous sparse approximations of said signal or signals;
- c. comparing the resulting structure books to structure books of known signatures.
