Method for object recognition
First Claim
1. A method for recognizing an object that has a plurality of expressions of abstract object characteristics, and is associated with an object characteristic class of a hierarchical system of object characteristic classes stored in a first memory;
- said method comprising;
1.1) observing at least one location at which the object is presumed to be present, using a plurality of sensors in a sensor suite, each of said sensors responding to at least one object characteristic, and accordingly emitting a sensor signal;
1.2) checking whether each of the emitted sensor signals exceeds a specified threshold value for the sensor signals, accepting sensor signals which exceed the threshold value, and storing the accepted sensor signals in a second memory;
1.3) pairing combinations of the sensor characteristics for the accepted sensor signals obtained in 1.2) to form identification characteristic pairs;
1.4) comparing the identification characteristic pairs obtained in 1.3) to the object characteristic classes stored in the first memory; and
1.5) identifying the object, based on the object characteristic class, whose object characteristic pairs are identical to the identification characteristic pairs obtained in 1.3).

Abstract
A method for recognizing an object that has a plurality of expressions of abstract object characteristics, and is associated with an object characteristic class of a hierarchical system of object characteristic classes stored in a first memory. The method includes i) observing at least one location at which the object is presumed to be present, using a plurality of sensors in a sensor population, each of said sensors responding to at least one object characteristic and accordingly emitting a sensor signal; ii) checking whether each of the emitted sensor signals exceeds a specified threshold value for the sensor signals, and accepting sensor signals which exceed the threshold value; iii) pairing combinations of the sensor characteristics, for the accepted sensor signals obtained in ii) to form identification characteristic pairs; iv) comparing the population of identification characteristic pairs obtained in iii) to the object characteristic classes stored in the first memory; and v) identifying the object, based on the object characteristic class, whose object characteristic pairs are identical to the identification characteristic pairs obtained in iii).

12. A system for recognizing an object that has a plurality of expressions of abstract object characteristics, and is associated with an object characteristic class of a hierarchical system of object characteristics classes;
- said system comprising;
a first memory having said hierarchical system of object classes stored therein; a plurality of sensors, each of which responds to at least one object characteristic and emits a corresponding sensor signal; a data processor; and a non-transitory computer readable medium encoded with a series of commands which cause the system to perform following steps; 1.1) said plurality of sensors observing at least one location at which the object is presumed to be present; 1.2) checking whether each of the emitted sensor signals exceeds a specified threshold value for the sensor signals, accepting sensor signals which exceed the threshold value, and storing the accepted sensor signals in a second memory; 1.3) pairing combinations of the sensor characteristics for the accepted sensor signals obtained in 1.2) to form identification characteristic pairs; 1.4) comparing the identification characteristic pairs obtained in 1.3) to the object characteristic classes stored in the first memory; and 1.5) identifying the object, based on the object characteristic class, whose object characteristic pairs are identical to the identification characteristic pairs obtained in 1.3). - View Dependent Claims (13, 14, 15, 16)
