    摘要： A system and method of face recognition is provided. The method includes capturing an image including a face and registering features of the image to fit with a model face to generate a registered model face. The registered model face is then transformed to a desired orientation to generate a transformed model face. The transformed model face is then compared against a plurality of stored images to identify a number of likely candidates for the face. In addition, the face recognition process may be performed passively.

    摘要： A system and method for tracking the movements of persons. The system includes at least two video devices and a computing device. The computing device is coupled to the at least two video devices and it includes a computing section capable of performing calculations to support mode stratified particle filtering. The method includes visually capturing a scene encompassing one or more strata, re-sampling each of the stratum, and redefining each of the stratum. The method further includes adding new or subtracting old strata based upon the arrival or departure of isolated targets within the scene and normalizing each of the stratum.

    摘要： A wearable security system integrates sensors, such as optical and acoustic sensors, a decision engine processor, a communications device, such as a cellular telephone, a location determination device, such as a GPS system, a device controller, and user feedback. A method of wearable security operates the wearable security system so that a user is aware of and able to control and interact with his or her environment, such as providing notice of potential threats or taking protective actions.

    摘要： A system for detecting and counting individuals in a stationary or moving crowd based on a digital or digitized image captured from a single camera. Initial information is assumed based on a foot-to-head plane homology, where a geometric construct is developed to best enclose image features with a high probability of being an individual within a crowd. These geometric constructs are then subjected to further probabilistic analysis to determine individuals. The vector track of each individual is determined to validate the determination of a group of features as individuals, thereby compensating for occlusion of an individual within any given frame image. A virtual gate is then employed to count the individuals moving past the virtual gate. Also, by weighting portions of the individual, events near the gate can be predicted.
