A system and method for classifying facial image data, the method comprising the steps of: training a classifier device for recognizing one or more facial images and obtaining corresponding learned models the facial images used for training; inputting a vector including data representing a portion of an unknown facial image to be recognized into the classifier; classifying the portion of the unknown facial image according to a classification method; repeating inputting and classifying steps using a different portion of the unknown facial image at each iteration; and, identifying a single class result from the different portions input to the classifier.

An imaging-based bar code reader that includes an item guide to guide movement of an item including a target bar code such that target bar code passes through a field of view of the reader in a straight line. The reader further includes an imaging and decoding system to: 1) capture a series of images which include at least a part of the target bar code as the bar code is moved through the field of view of the reader; 2) sequentially analyze the series of captured images, for each captured image, identifying areas of the captured image representative of an image of the target bar code and decode decodable portions of the imaged target bar code; and 3) combining the decoded portions of the imaged target bar code using a sequence stitching method to obtain a full decode of the target bar code.

Described is a system and method for optical character recognition in an image. The method comprising identifying a connected component in an image, computing at least one parameter for the connected component and selecting a portion of the image corresponding to the connected component for optical character recognition when the at least one parameter is within a predetermined threshold range.

A method and apparatus are disclosed for modeling patterns of behavior of humans or other animate objects and detecting a violation of a repetitive pattern of behavior. The behavior of one or more persons is observed over time and features of the behavior are recorded in a multi-dimensional space. Over time, the multi-dimensional data provides an indication of patterns of human behavior. Activities that are repetitive in terms of time, location and activity, such as sleeping and eating, would appear as a Gaussian distribution or cluster in the multi-dimensional data. Probability distribution functions can be analyzed using known Gaussian or clustering techniques to identify repetitive patterns of behavior and characteristics thereof, such as a mean and variance. Deviations from repetitive patterns of behavior can be detected and an alarm can be triggered, if appropriate.

Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by ensuring that such markings are read in the vicinity of an ideal, focused, target plane, and by enhancing the contrast of such markings. Calibration and self-calibration of the reader improve performance.
摘要:
An apparatus for detecting an emergency/law enforcement vehicle from a secondary vehicle. The apparatus includes: at least one camera mounted on the secondary vehicle; a display surface mounted inside an interior of the secondary vehicle for displaying video image data from the at least one camera; at least one of a pan, tilt, and zoom motor operatively connected to the at least one camera for providing an enhanced view of an emergency/law enforcement vehicle displayed on the display surface; and a controller for controlling the at least one pan, tilt, and zoom motors to provide the enhanced view. The apparatus alternatively also has the capability to detect, track and/or classify an emergency/law enforcement vehicle in the video image data.
摘要:
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.
摘要:
A method for recommending a video content to a viewer. The method including the steps of: determining a user profile of the viewer, the user profile indicating the viewing preferences of the viewer, providing a plurality of user profiles; comparing the user profile of the viewer to each of the plurality of user profiles to determine if each of the plurality of user profiles contains at least one common characteristic with the user profile of the viewer; and determining a recommendation for the video content based on the plurality of user profiles, wherein user profiles having the at least one common characteristic are assigned a greater recommendation weight than user profiles not having the at least one common characteristic.
摘要:
A telephone user who is at a first telephone station and is placed on hold at a second station is prevented from listening to an objectionable audio signal while a call is in process between the user and the second telephone station. The objectionable audio signal is detected while the call is in process and the user is prevented from hearing the objectionable audio signal while the objectionable audio signal is being detected. In response to detection of the end of the objectionable audio signal, the user is coupled to the second telephone station.

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.
