A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.

System and method for server based control

A system and method tracks the movements of a driver or passenger in a vehicle (ground, water, air, or other) and controls devices in accordance with position, motion, and/or body or hand gestures or movements. According to one embodiment, an operator or passenger uses the invention to control comfort or entertainment features such the heater, air conditioner, lights, mirror positions or the radio/CD player using hand gestures. An alternative embodiment facilitates the automatic adjustment of car seating restraints based on head position. Yet another embodiment is used to determine when to fire an airbag (and at what velocity or orientation) based on the position of a person in a vehicle seat. The invention may also be used to control systems outside of the vehicle. The on-board sensor system would be used to track the driver or passenger, but when the algorithms produce a command for a desired response, that response (or just position and gesture information) could be transmitted via various methods (wireless, light, whatever) to other systems outside the vehicle to control devices located outside the vehicle. For example, this would allow a person to use gestures inside the car to interact with a kiosk located outside of the car.

Tracking and gesture recognition system particularly suited to vehicular control applications

A system for recognizing various human and creature motion gaits and behaviors is presented. These behaviors are defined as combinations of “gestures” identified on various parts of a body in motion. For example, the leg gestures generated when a person runs are different than when a person walks. The system described here can identify such differences and categorize these behaviors. Gestures, as previously defined, are motions generated by humans, animals, or machines. Multiple gestures on a body (or bodies) are recognized simultaneously and used in determining behaviors. If multiple bodies are tracked by the system, then overall formations and behaviors (such as military goals) can be determined.

Behavior recognition system

A system using passive infrared imaging of the face and other body parts of an operator to obtain observables by automatically extracting features from a sequence of images, analyzing the extracted features, and then assessing the results for indicators of performance of a task by the operator in order to provide early warning of potential cognitive or motor impairment and thereby facilitate risk reduction and quality maintenance. The infrared condition monitoring system (IR-CMS) serves to a) assess cognitive and/or physical readiness to perform a particular task; b) provide condition assessment feedback to the subject and his appropriate supervisors; c) activate measures to increase short-term alertness and other readiness factors; d) limit potential risks by restricting the subject's access, responsibility, or authority; and e) facilitate rapid medical treatment, evacuation, quarantine, re-training, or counseling as appropriate. The same condition monitoring and assessment system can also be used during training and simulator exercises to evaluate personnel for assignment.

Method and apparatus for operator condition monitoring and assessment

A method and system for physiological gating is disclosed. A method and system for detecting and predictably estimating regular cycles of physiological activity or movements is disclosed. Another disclosed aspect of the invention is directed to predictive actuation of gating system components. Yet another disclosed aspect of the invention is directed to physiological gating of radiation treatment based upon the phase of the physiological activity. Gating can be performed, either prospectively or retrospectively, to any type of procedure, including radiation therapy or imaging, or other types of medical devices and procedures such as PET, MRI, SPECT, and CT scans.

Method and system for predictive physiological gating

A method is provided for detecting a human face in an image, such as a sequence of images supplied by a video camera. The method comprises locating in each image a candidate face region and analyzing the candidate face region for a first characteristic indicative of a facial feature. The locating step may comprise detecting uniformity saturated regions of predetermined shape in a reduced resolution version of the image. The analyzing step may comprise selecting a signal color component, forming a vertical integral projection profile and detecting an omega shape in the profile characteristic of an eye region of a face.

Method of and apparatus for detecting a human face and observer tracking display

An image tracking system which is configured to present a sequence of images, determine the position of a target image in a previously presented image, determine movement of the target image between the previously presented image and a subsequently presented image, and indicate the position of the target image in the subsequently presented image as the aforementioned determined position modified by the determined movement.

Image tracking system and method and observer tracking autostereoscopic display

A method of detecting a face-like region of a colour image, comprises reducing the resolution of the colour image by averaging the saturation to form a reduced resolution image and searching for a region of the reduced resolution image. The searched region has, in a predetermined shape, a substantially uniform saturation which is substantially different from the saturation of the portion of the reduced resolution image surrounding the predetermined shape.

of EP0984386A method is provided for detecting a human face in an image, such as a sequence of images supplied by a video camera (3). The method comprises locating (17) in each image a candidate face region and analysing (18) the candidate face region for a first characteristic indicative of a facial feature. The locating step (17) may comprise detecting (S23) uniformly saturated regions of predetermined shape in a reduced resolution version of the image. The analysing step (18) may comprise selecting a single colour component (S10), forming a vertical integral projection profile and detecting (S31) an omega shape in the profile characteristic of an eye region of a face.

Method of detecting a human face

PROBLEM TO BE SOLVED: To provide a method and device for automatically detecting a human face in an input video image stream or sequence. SOLUTION: A method for detecting a human face in an image comprises a step for finding a facial candidate area in an image and a step for analyzing the facial candidate area related to the first characteristics indicating the characteristics of a face. The first characteristics include almost symmetrical horizontal luminance curved graphics including the maximum value arranged between first and second minimum values. Also, the analytic step comprises a step for forming the vertical integral projection of one part of the facial candidate area and a step for judging whether or not the vertical integral projection has the first and second minimum values arranged almost symmetrically to the maximum value.
