Abstract: An example apparatus for detecting objects in video frames includes a receiver to receive a plurality of video frames from a video camera. The apparatus also includes a first still image object detector to receive a first frame of the plurality of video frames and calculate localization information and confidence information for each potential object patch in the first frame. The apparatus further includes a second still image object detector to receive an adjacent frame of the plurality of video frames adjacent to the first frame and calculate localization information and confidence information for each potential object patch in the adjacent frame. The apparatus includes a similarity detector trained to detect paired patches between the first frame and the adjacent frame based on a comparison of the detected potential object patches.

Abstract: In one embodiment, a method includes receiving a unique identifier of a second user from a mobile client system of a first user after the second user requests to communicate with the first user, identifying the second user based on the unique identifier, retrieving multiple items of profile information of the second user, determining whether the unique identifier is in a list of blocked identifiers, and sending to the first user a notification that a communication request form the second user has been declined if the unique identifier is in the list of blocked identifiers. The method also includes sending the first user multiple items of profile information of the second user if the unique identifier is in the list of blocked identifiers.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user of an online social network, an unique identifier associated with a second user of the online social network, the unique identifier being sent responsive to a communication between the second user and the first user, accessing a social graph including first and second nodes corresponding to the first and second users, respectively, identifying the second user based on the unique identifier, retrieving profile information associated with the second user and a privacy setting associated with the second user, determining whether the information is visible to the first user based on the privacy setting and a degree of separation in the social graph between the first node and the second node, and sending, to the client system, the profile information that is visible to the first user for display in association with the communication.

Abstract: An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. In one illustrative implementation, the communication infrastructure may rely, in part, on wireless communication. The device may correspond to a book reader device or other type of device.
