摘要： A system and method of authentication is provided that uses the spatiotemporal context of a user which has been measured using third party monitoring systems. Spatiotemporal data obtained from third party systems such as CCTV networks, ATM networks or the like is used to determine a unique spatiotemporal fingerprint for an individual. That is, the unique identifier is not derived from a device carried by the individual. This fingerprint can then be used to verify a user and detect abnormal and unexpected behaviour.

摘要： Methods and apparatus for capturing motion from a self-tracking device are disclosed. In embodiments, a device self-tracks motion of the device relative to a first reference frame while recording motion of a subject relative to a second reference frame, the second reference frame being a reference frame relative to the device. In the embodiments, the subject may be a real object or, alternately, the subject may be a virtual subject and a motion of the virtual object may be recorded relative to the second reference frame by associating a position offset relative to the device with the position of the virtual object in the recorded motion. The motion of the subject relative to the first reference frame may be determined from the tracked motion of the device relative to the first frame and the recorded motion of the subject relative to the second reference frame.

摘要： Es wird eine Kamera (10) zur Erfassung von in einer Förderrichtung (34) bewegten Objekten (32) angegeben, die einen Lichtempfänger (20) mit zumindest zwei Zeilen (22a-b) von Lichtempfangspixeln (24) sowie eine Steuer- und Auswertungseinheit (26) aufweist. Mit den beiden Zeilen (22a-b) werden zwei gegeneinander zumindest in Zeilenrichtung versetzte Aufnahmen (40a-b) eines Teilbereich des Objekts (32) erzeugt und daraus eine Bildzeile mit erhöhter Auflösung berechnet. Aus den im Laufe der Bewegung der Objekte (32) erzeugten Bildzeilen wird ein Gesamtbild zusammengesetzt. Dem Lichtempfänger (20) ist eine Empfangsoptik (16) vorgeordnet, die für den Versatz zwischen den Aufnahmen (40a-b) sorgt.

摘要： An image of an eye is obtained via a camera. A multi-step filter is applied to the image for multiple iterations. Applying the multi-step filter includes, for each iteration, performing one or more pixel merge operations on the image. The pixel merge operations are controlled based on one or more input parameters to control whether or not the iteration classifies pixels of the image as corresponding to a feature of the eye. The one or more input parameters vary from at least one iteration to another. The iterations each output a provisional output, in which some pixels of the image are deemed as corresponding to the feature of the eye. The provisional outputs provide diverse definitions of the eye feature, and may be combined in various ways to yield a refined output, in which some pixels of the image are deemed as corresponding to the feature of the eye.

摘要： A method is disclosed of processing a sequence of video frames showing motion of a subject to compare the motion of the subject with a reference motion. The method comprises storing at least one reference motion data frame defining a reference motion, each reference motion data frame corresponding to respective first and second reference video frames in a sequence of video frames showing the reference motion and comprising a plurality of optical flow vectors, each optical flow vector corresponding to a respective area segment defined in the first reference video frame and a corresponding area segment defined in the second reference video frame and defining optical flow between the area segment defined in the first reference video frame and the area segment defined in the second reference video frame. The method further comprises receiving a sequence of video frames to be processed. The method further comprises processing at least one pair of the received video frames to generate a motion data frame defining motion of a subject between the pair of received video frames. Each pair of received video frames that is processed is processed by, for each area segment of the reference video frames, determining a corresponding area segment in a first video frame of the pair and a corresponding area segment in a second video frame of the pair. Each of the pairs of received video frames is further processed by, for each determined pair of corresponding area segments, comparing the area segments and generating an optical flow vector defining optical flow between the area segments. Each of the pairs of received video frames is further processed by generating a motion data frame for the pair of received video frames, the motion data frame comprising the optical flow vectors generated for the determined pairs of corresponding area segments. The method further comprises comparing the at least one reference motion data frame defining the reference motion to the at least one generated motion data frames defining the motion of the subject and generating a similarity metric for the motion of the subject and the reference motion.

摘要： By correlating user grip information with micro-mobility events, electronic devices can provide support for a broad range of interactions and contextually-dependent techniques. Such correlation allows electronic devices to better identify device usage contexts, and in turn provide a more responsive and helpful user experience, especially in the context of reading and task performance. To allow for accurate and efficient device usage context identification, a model may be used to make device usage context determinations based on the correlated gesture and micro-mobility data. Once a context, device usage context, or gesture is identified, an action can be taken on one or more electronic devices.

摘要： A gesture recognition method and an apparatus are provided. The method is applied to a terminal device based on a mobile communications network signal, the terminal device stores training sample data, and the training sample data includes a correlation spectrum characteristic vector of a reflected signal of a sounding reference signal SRS and a corresponding user gesture identifier. The method includes: transmitting, by the terminal device, a first sounding reference signal SRS; receiving, by the terminal device, a multipath reflected signal that is of the first sounding reference signal SRS and that is reflected from a gesture-making object, and performing a related operation on the reflected signal and a signal template corresponding to the first sounding reference signal SRS, to obtain a correlation spectrum characteristic vector of the reflected signal; and matching, by the terminal device, the correlation spectrum characteristic vector of the reflected signal against the training sample data, to recognize an input gesture.

摘要： A device for detecting and recording animal behavior is provided. The device includes at least one corral that defines a contained field, the base surface of the at least one corral being sensitive to the animal's footprint. The device also includes an image capturing device that cooperates with the base surface to capture both a profile of the animal's full footprint and a profile of the animal's toe print when the animal is standing on its toes. In some embodiments, a first light is totally internally reflected within the base surface and a second light illuminates at least one of a tail, body and head of the animal from below the animal. In some embodiments, the first and second lights are produced from first and second light sources.
