A ball-throwing machine includes a camera connected to a computer vision unit and a microphone connected to a speech-processing unit. The computer vision unit processes images from the camera to determine a user's position, and to detect user gestures from a predetermined repertoire of gestures. The speech-processing unit recognizes user vocal commands from a predetermined repertoire of commands. A computer receives information from a control panel, from the computer vision unit, from the speech-processing unit, and from a file describing the ballistic properties of the ball to be thrown. The computer accordingly determines a ball trajectory according to the user's position and parameters indicated by a combination of control-panel settings, user gestures, and user vocal commands. The computer then adjusts the direction, elevation, ball speed, and ball spin to conform to the determined trajectory, and initiates throwing of a ball accordingly.

A monitoring system for an infant, child, invalid, or other person requiring care uses computer vision and hearing, and inputs of other modalities, to analyze the status of a caretaker and/or cared-for person and its environment. The conditions are classified as normal or alarm conditions and an informative alarm signal is generated which may include records of the vision audio and other inputs. The system also has the ability to solicit responses from the occupants to stimulate a classifiable input to reduce ambiguity in its state signal.

A camera-based system includes a number of sites, each having a camera associated therewith. A processing system processes a video signal received from a camera at a given one of the sites, and provides a controlled switching between a representative presence mode and at least one other mode for presentation, at one or more of the sites remote from the given site, of corresponding output video associated with the given site. The processing system utilizes information derived from the video signal generated by the camera to control the switching between the representative presence mode and the other mode, which may be, e.g., a live video mode. For example, the processing system may process the video to identify a user of the system, retrieve a corresponding user profile, and control the switching between the modes in accordance with information in the retrieved user profile.

A method for reacquiring a target in an automated video tracking system is provided. The method includes the steps of: selecting a desired target to be tracked; switching the automated video tracking system to an automatic mode to initiate a tracking sequence to automatically track the selected desired target; switching the automated video tracking system from an automatic mode to a manual mode if the automated video tracking system encounters a period of difficulty in tracking the desired target; reacquiring the desired target in manual mode; and switching the automated video tracking system to the automatic mode for automatic tracking of the reacquired desired target without initiating a new tracking sequence. An apparatus and automated video tracking system for carrying out the methods of the present invention are also provided.

A method for selecting a target in an automated video tracking system. The method including the steps of: displaying video image data of a scene having a target to be tracked; freezing the video image data to display a frame thereof; and selecting a desired target in the frame of the video image data. Also provided is an apparatus for selecting a target in an automated video tracking system and an automated video tracking system employing such methods and apparatus.
摘要:
A system and method that detects and identifies an event from a sequence of images received. The system comprises a control unit that receives and processes the sequence of images from the camera. The control unit identifies at least one stationary image prior to the event and one stationary image subsequent to the event. The control unit compares one or more representations corresponding to one or more edges in the first stationary image with one or more representations corresponding to one or more edges in the second stationary image to determine whether an object has been deposited or removed during the event.

A security monitoring system including: an alarm system having detectors for detection of an alarm in a structure; at least one camera for capturing image data inside and/or outside the structure; a processor for selecting a subset of the image data upon the occurrence of the alarm based on a predetermined criteria; and a modem for transmitting the subset of image data to a remote location. Preferably, the processor ranks each video frame from the image data according to how well each video frame meets the predetermined criteria and the modem transmits a predetermined number of video frames having the best rank to the remote location.
摘要:
A video content analysis system extends content analysis capability of one system to multiple channels by providing for the spatial multiplexing of the multiple channels and appropriately analyzing the spatially multiplexed video signal. The resulting system may be lower in cost that present systems and permit the system to work with ancillary equipment such as video recorders. The system also preserves the real-time information inherent in the multiple source signals.

摘要:
A method includes obtaining image data for a patient. The image data corresponds to acquisition data from an imaging acquisition from a set of planned image acquisitions in an examination plan for the patient. The method further includes analyzing the image data with a processor based on an imaging practice guideline and producing electronically formatted data indicative of the analysis. The processor generates a signal indicative of a recommendation of a change to the examination plan based on the data indicative of the analysis.
