International Classification:

G01R 27/00

US Classification:

324600000

Abstract:

An electrical component and material with fractional order impedance, as well as electrical circuits for use in fractional order calculus for automated signal processing are provided. Fractional order methods can be particularly important in solving nonlinear problems, such as performing automatic control, pattern recognition, system characterization, signal processing, and modeling.

International Classification:

G06K 9/00

US Classification:

382103

Abstract:

A method and system for tracking moving objects in a scene is described. One embodiment acquires a digital video signal corresponding to the scene; identifies in the digital video signal one or more candidate moving objects; locates at least one candidate moving object in the digital video signal subsequent to identification of the at least one candidate moving object; tracks candidate moving objects that, for at least a predetermined period after they have been identified, continue to be located in the digital video signal; assigns a score to each tracked candidate moving object in accordance with how long after passage of the predetermined period the tracked candidate moving object has continued to be located in the digital video signal; combines the respective scores of the tracked candidate moving objects to obtain an overall score for the scene; and indicates to a user whether the overall score satisfies a predetermined criterion.
