Abstract
In one implementation, a graphical object classification system includes an acquisition module, a signature generation module, and a classification module. The acquisition module accesses a representation of a graphical object. The signature generation module generates an appearance-invariant signature of the graphical object based on the representation. The classification module classifies the graphical object based on the appearance-invariant signature.
Claims16
A graphical object classification system, comprising:
- an acquisition module to access a representation of a graphical object;
- a signature generation module to generate an appearance-invariant signature of the graphical object based on the representation of the graphical object;
- and
- a classification module to classify the graphical object based on the appearance-invariant signature.
A processor-readable medium storing code representing instructions to cause a processor to perform a process, the process comprising:
- receiving a plurality of graphical object representations, each graphical object representation associated with a graphical object from a plurality of graphical object, each graphical object associated with an object class from a plurality of object classes;
- generating a plurality of appearance-invariant signatures, each appearance-invariant signature based on the graphical object representation of a graphical object from the plurality of graphical objects and associated with that graphical object;
- and
- classifying each graphical object into an object class from the plurality of object classes based on the appearance-invariant signature associated with that graphical object.
A graphical object classification method, the process comprising:
- accessing a representation of a graphical object;
- defining a plurality of signature vectors from the representation;
- and
- combining each signature vector from the plurality of signature vectors to define an appearance-invariant signature of the graphical object.
