摘要:
An aiming pattern assembly (60) for an imaging-based bar code reader (10) including: a light source assembly (62) generating focused light; a pattern shaping assembly (66) receiving focused light from the light source assembly (62) and including a first area (66a) and a non-overlapping second area (66b), focused light passing through the first area (66a) creating a first aiming pattern (P1) projected toward a field of view (FV) and passing through the second area (66b) creating a second aiming pattern (P2) projected toward the field of view (FV); and a pattern selection assembly (68) receiving the first and second aiming patterns (P1, P2) and passing at least one of the first and second aiming patterns (P1, P2).
摘要:
A system and method for performing a read operation including acquiring a series of frames of image data; processing a first frame of image data including an array of pixel data acquired while an aiming pattern was generated for determining a location L of at least one pixel of the array of pixel data that corresponds to the aiming pattern; and processing a second frame of image data acquired while the aiming pattern was not generated. The processing of the second frame of image data includes the steps of selecting at least one optical code acquired in the second frame of image data that is located at a respective location; wherein the respective location meets a predetermined condition relative to the determined location L; and providing the selected at least one optical code for further processing in accordance with the read operation.
摘要:
A system and method is provided for selectively activating biometric sensors (102, 104, 106) to authenticate the identity of an individual while conserving system resources. A biometric system has at least two tiers of sensors, first (102) and second tier sensors (104, 106), where the first tier sensors (102) are characteristically less sophisticated and less expensive to operate than the second tier sensors (104, 106). One or more of the second tier sensors (104, 106) are activated only after a user's biometric is successfully or unsuccessfully verified by one of the first tier sensors (102). Alternatively, the second tier sensors (104, 106) are activated in response to a user requesting a particular level of service or in response to an environmental condition. Alternatively, only those sensors are turned on which are compatible with a user's biometric profile.
摘要:
A system 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.

Methods, systems, and apparatuses for identifying items carried by a mobile structure are described. At a first location of the mobile structure, a first radio frequency identification (RFID) read signal is directed to a load carried by the mobile structure to identify an initial set of RFID tags. At a subsequent location of the mobile structure, a subsequent read signal is directed to the load carried by the mobile structure to identify a subsequent set of RFID tags. The initial set of RFID tags and the subsequent set of RFID tags are compared to determine a set of RFID tags associated with the load.
摘要:
Using known methods of face recognition, appliances can be automatically initiated and/or adjusted as a user enters an environment, such as a home or a room. The environment is networked such that there is a communication link between a camera monitoring the entrance to the environment, a face recognition system, and the appliances. The method of automatically controlling a networked environment includes capturing a face image of an individual, storing the face image (i.e., in a memory), and associating at least one appliance setup to the face image. The method also includes comparing the face image to stored face images, retrieving the at least one appliance setup for a matched face image, and initiating the at least one appliance setup. An appliance setup controls turning on or off an appliance, such as an illumination source, a television, or a stereo.
摘要:
An identification and/or verification system which has improved accuracy when the expression on the face of the captured image is different than the expression on the face of the stored image. One or more images of a person are captured. The expressive facial features of the captured image are located. The system then compares the expressive facial features to the expressive facial features of the stored image. If there is no match then the locations of the non-matching expressive facial feature in the captured image are stored. These locations are then removed from the overall comparison between the captured image and the stored image. Removing these locations from the subsequent comparison of the entire image reduces false negatives that result from a difference in the facial expressions of the captured image and a matching stored image.

摘要:
A monocular input image is transformed to give it an enhanced three dimensional appearance by creating at least two output images. Foreground and background objects are segmented in the input image and transformed differently from each other, so that the foreground objects appear to stand out from the background. Given a sequence of input images, the foreground objects will appear to move differently from the background objects in the output images.
摘要:
An image processing system is disclosed that provides automatic face or skin blurring for images. All faces or skin can be blurred, or specific faces can be blurred. In one aspect of the invention, a particular face is blurred on an image or on a series of images in a video. Faces are determined in an image, and face matching is performed to match a particular face to faces in the image. If a match is found, the face or a portion of the face is blurred in the image. The blurring is performed on a portion of the image containing the particular face. Blurring may be performed through a variety of techniques. In another aspect of the invention, voice processing is used as an adjunct to or in place of face analysis to determine if a face in an image or series of images should be blurred. In another aspect of the invention, all faces or human skin in an image or series of images is blurred.
