Patent ID: 6859707

Claim:
A device for classifying persons and objects, comprising: a first arrangement for acquiring characteristic data on one of a person and an object to be classified; a second arrangement for executing at least one algorithm for extracting features from instantaneously acquired characteristic data; at least one filter for determining a classification of one of the person and the object from instantaneously extracted features, wherein the at least one filter takes into account progression of previously extracted features over time for the one of the person and the object to be classified; and a first counter for initiating a resetting of the at least one filter when, during a first time interval specified by the first counter, the at least one algorithm has exclusively supplied features for an absence of the one of the person and the object; a holding member arranged downstream from the at least one filter for outputting the classification determined by the at least one filter; and a second counter for initiating a resetting of the holding member if the at least one algorithm only supplies features for the absence of the one of the person and the object, even after a second time interval specified by the second counter has elapsed.
