Abstract: Vision based system and method for detecting a breach of security in a monitored area. One or more sequences of events are stored in the system. Each sequence of events includes a different combination of events and an order in which the events have occurred. An action is associated with each sequence of events such as triggering an alarm, generating an audible sound, calling 911 etc. when the events detected by the system match a given sequence the action associated with that sequence is performed. The system receives an image stream of the area and detects the events occurring in the images including the detection of a human body, its size and location within the monitored area. The system may be activated at all time without requiring people in the monitored area to change their normal behavior.

Abstract: A system and method for detecting a distress condition of a person in a monitored location. The system is configured to receive an image stream of the monitored location, and detect a human body or body part within the monitored location. The system maintains and updates a list of areas in which the lack of movement is permitted, e.g., bed, sofa, chairs. Upon detecting that the person is no longer moving and exists in a new area that is not in the list of areas, the system enters into an acknowledgement session in which the system asks the person to perform a certain action if everything is fine. If the given action is detected within a pre-determined period the system updates the list of areas to add the new area therein, otherwise the system would execute a pre-defined function representing a response to the distress condition, e.g., call 911.

Abstract: Image based operating systems and methods are provided that identify objects in video data and then take appropriate action in a wide variety of environments. In some embodiments, the image based operating systems and methods allow a user to activate other devices and systems by making a gesture.

Abstract: System and method which allow a user to interface with a machine/computer using an image capturing device (e.g. camera) instead of conventional physical interfaces e.g. keyboard, mouse. The system allows the user to interface from any physical and non-physical location within the POV of the camera at a distance that is determined by the resolution of the camera. Using images of the hand, the system may detect a change of hand states. If the new state is a known state that represents a hit state, the system would map the change of state to a key hit in a row and column of the keyboard and sends the function associated with that key for execution. In an embodiment, the system determines the row based on the rotation of the wrist and/or position of the hand.

Abstract: The present document describes a method for authenticating a user into a system using gestures. The user may draw the gesture on a touch sensitive device (e.g. touchpad), or make the gesture in the air in front of a camera. In the touchpad embodiment, the trajectory defined by the gesture is received ready from the touchpad. In the camera embodiment, the trajectory is built by analyzing the images of an image stream to find a hand (or another subject i.e. meta-subject). The trajectory may then be built by monitoring the change of position of the hand in the succession of images. The trajectory is analyzed to determine the key-code defined by the gesture, and to determine whether or not it is the authenticated user who is performing the gesture (as opposed to an intruder) based on the speed and the distance between the trajectory and a straight line.

Abstract: A vision-based operating system is provided in which a computer-based system accepts visual inputs and takes appropriate actions in a wide variety of environments. One environment is a security environment in which the vision-based operating system acquires an image of a face and determines, with an arbitrarily small probability of a false positive, whether the face is of a person who is authorized to enter the environment. The method employed may include acquiring a digital image for comparison to a reference image and identifying two or more groups of pixels in the acquired image. The pixel groups in the reference image that are the best match for the two or more pixels groups in the acquired image are selected. The relative locations of the selected pixel groups in the reference image and the two or more pixel groups in the acquired image are compared, and the probability that the relative locations occurred randomly is determined.

A method and a computer-readable storage medium are also described and claimed.

Abstract: A method for transforming a first image defined by a first multi-dimensional color space (RGB) into second image defined by a second multi-dimensional color space (CMYK). The method computes the transformation using information derived from a previous transformation of said second image into said first image. The method then minimizes the error produced while transforming the second image back into the first image. As such, an image editing system can display on a video monitor an image that is defined in one multi-dimensional color space (RGB), print using a printer that prints images using a second multi-dimensional color space (CMYK) and edit an image using any multi-dimensional color space (either RGB or CMYK) that facilitates rapid and accurate image editing.

Abstract: A method for image processing in a computerized system reduces the amount of memory required for image processing and produces a layered effect which permits complex manipulation such as scaling and rotation without long delay, while allowing earlier versions of the visual image to be recalled. The method involves pre-processing, image editing and raster image processing.
