Abstract
Abstract A method and system are provided for distinguishing objects. Signals representative of the objects are input (63). From the signals, measurements of multiple types are acquired (64). At least one of the measurement types is continuously variable. In response to the measurements, respective amounts of mutual information of the measurement types are determined (70). In response to the respective amounts of mutual information, at least one measurement type is selected for evaluation in distinguishing the objects (72).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A system for distinguishing objects, comprising: inputting circuitry for inputting first signals representative of the objects; acquiring circuitry coupled to said inputting circuitry for acquiring measurements of a plurality of measurement types from said first signals, at least one of said measurement types being continuously variable; determining circuitry coupled to said acquiring circuitry for determining respective amounts of mutual information of said measurement types in response to said measurements; selecting circuitry coupled to said determining circuitry for selecting, in response to said respective amounts, a measurement type of said measurement types, and; ordering circuitry coupled to said selecting circuitry for ordering each of said selected measurement types in an n-ary decision tree having branches for evaluation in distinguishing the object, where n is at least 3 and wherein said branches are only directly connected to a parent of said branches, adjacent branches being separated by a threshold value of said measurements.
Claim 2
Independent Claim
151 words
A system for distinguishing objects, comprising: inputting circuitry for inputting first signals representative of the objects; acquiring circuitry coupled to said inputting circuitry for acquiring measurements of a plurality of measurement types from said first signals, at least one of said measurement types being continuously variable; determining circuitry coupled to said acquiring circuitry for determining respective amounts of mutual information of said measurement types in response to said measurements; selecting circuitry coupled to said determining circuitry for selecting, in response to said respective amounts, a measurement type of said measurement types, and; ordering circuitry coupled to said selecting circuitry for ordering each of said selected measurement types in an n-ary decision tree having branches for evaluation in distinguishing the object, where n is at least 3 and wherein said branches are only directly connected to a parent of said branches, adjacent branches being separated by a threshold value of said measurements.
Claim 3
Dependent Claim
54 words
The system as in claim 1, wherein said system further comprises evaluating circuitry coupled to said selecting circuitry for evaluating, in response to said selected measurement type, at least one measurement from a set of second signals from a location for distinguishing at least one of the objects as being represented in said set.
Claim 4
Dependent Claim
25 words
The system as in claim 2, wherein said evaluating circuitry is operable to distinguish said at least one of the objects with a specified reliability.
Claim 5
Dependent Claim
46 words
The system of claim 1, wherein said ordering circuitry is further operable to quantized each of said selected measurement type to form quantized measurement types being continuously variable, such that said decision tree includes each of said quantized measurement types for evaluation in distinguishing the objects.
Claim 6
Dependent Claim
53 words
The system of claim 1, wherein said system further comprises circuitry coupled to said ordering circuitry for traversing a path of said decision tree, such that multiple measurements from a set of second signals from a location are evaluated for distinguishing at least one of the objects as being represented in said set.
Claim 7
Dependent Claim
45 words
The system as in claim 1, wherein said system further comprises establishing circuitry coupled to said inputting circuitry for establishing, in response to a representation of the objects in said first signals, initial probabilities of the objects being represented in a set of second signals.
