    摘要: A network-based data protection scheme for a mobile device utilizes encryption techniques and a remote key server that stores encryption keys on behalf of the mobile device. The mobile device stores encrypted data, preferably having no unencrypted counterpart stored therewith. On an as-needed basis, the mobile device requests a decryption key (or an encrypted version of a decryption key) from the key server, where the decryption key can be used by the mobile device to decrypt the encrypted information. The key server transmits the decryption key to the mobile device after authenticating the user of the mobile device.

    摘要: Multi-modal, multi-lingual devices can be employed to consolidate numerous items including, but not limited to, keys, remote controls, image capture devices, audio recorders, cellular telephone functionalities, location/direction detectors, health monitors, calendars, gaming devices, smart home inputs, pens, optical pointing devices or the like. For example, a corner of a cellular telephone can be used as an electronic pen. Moreover, the device can be used to snap multiple pictures stitching them together to create a panoramic image. A device can automate ignition of an automobile, initiate appliances, etc. based upon relative distance. The device can provide for near to eye capabilities for enhanced image viewing. Multiple cameras/sensors can be provided on a single device to provide for stereoscopic capabilities. The device can also provide assistance to blind, privacy, etc. by consolidating services.

    摘要: Described is a technology by which video, which may be relatively high-resolution video, is efficiently processed to determine whether the video contains a specified action. The video corresponds to a spatial-temporal volume. The volume is searched with a top-k search that finds a plurality of the most likely sub-volumes simultaneously in a single search round. The score volumes of larger spatial resolution videos may be down-sampled into lower-resolution score volumes prior to searching.

    摘要: Techniques and technologies for tracking a face with a plurality of cameras wherein a geometry between the cameras is initially unknown. One disclosed method includes detecting a head with two of the cameras and registering a head model with the image of the head (as detected by one of the cameras). The method also includes back projecting the other detected face image to the head model and determining a head pose from the back-projected head image. Furthermore, the determined geometry is used to track the face with at least one of the cameras.

    摘要: Described is labeling a video session with metadata representing a recognized person or object, such as to identify a person corresponding to a recognized face when that face is being shown during the video session. The identification may be made by overlaying text on the video session, e.g., the person's name and/or other related information. Facial recognition and/or other (e.g., voice) recognition may be used to identify a person. The facial recognition process may be made more efficient by using known narrowing information, such as calendar information that indicates who the invitees are to a meeting that is being shown in the video session.

    摘要: The computer-readable media provides improved procedures to estimate head motion between two images of a face. Locations of a number of distinct facial features are determined in two images. The locations are converted into as a set of physical face parameters based on the symmetry of the identified distinct facial features. An estimation objective function is determined by: (a) estimating each of the set of physical parameters, (b) estimating a first head pose transform corresponding to the first image, and (c) estimating a second head pose transform corresponding to the second image. The motion is estimated between the two images based on the set of physical face parameters by multiplying each term of the estimation objective function by a weighted contribution factor based on the confidence of data corresponding to the estimation objective function.
