Abstract
Methods and apparatus for performing efficient pattern matching in a client-server network are described herein. A communication device acquires an object to be matched. At least one reduced set of features is extracted from the object to be matched and a determination as to whether the object to be matched matches one of a plurality of known objects in a local library stored on the communication device is generated. An indication representing a match of the object is presented if the determination indicates a local match exists in the local library. A match request including the at least one reduced set of features is transmitted for a remote matching determination when the determination indicates that no local match exists in the local library. In accordance with some aspects, a series of one or more match requests may be transmitted for a remote matching determination.
