Apparatuses and methods associated with preserving authentication under item change are disclosed herein. In embodiments, acquiring digital image data of an image of at least a portion of a target physical object; extracting features from the image data to form a digital fingerprint; querying the database system to seek a matching record based on the digital fingerprint; based on an amount of difference between the digital fingerprint and a stored digital fingerprint of the database, update the database system to output a new indication of a new match to the physical object for any new samples that are not matchable to the stored digital fingerprint within a first predetermined similarity threshold provided the new samples are matchable to the digital fingerprint within a second predetermined similarity threshold. Other embodiments may be disclosed or claimed.

The present disclosure provides systems and methods that use and/or generate image files according to a novel microvideo image format. For example, a microvideo can be a file that contains both a still image and a brief video. The microvideo can include multiple tracks, such as, for example, a separate video track, audio track, and/or one or more metadata tracks. As one example track, the microvideo can include a motion data track that stores motion data that can be used (e.g., at file runtime) to stabilize the video frames. A microvideo generation system included in an image capture device can determine a trimming of the video on-the-fly as the image capture device captures the microvideo.

A display apparatus includes user input circuitry for receiving user commands and a display for displaying video content and a user interface. The video content includes metadata. The display apparatus includes a processor in communication with the user input circuitry and the display; and non-transitory computer readable media in communication with the processor that stores instruction code. The instruction code, when executed by the processor, causes the processor to receive, from the user input circuitry, a query regarding an image of the video content currently displayed on the display; and determine one or more objects of the image associated with the query based on the metadata. The processor updates the user interface to depict one or more controls, each control being associated with one of the determined one or more objects; and receives a selection of one of the controls. The processor then updates the user interface to depict information related to the selection.

A computer-implemented method of associating digital tags with digital files comprises storing a plurality of digital files having embedded therein content data and metadata including tags; receiving, via a user interface device of a client device, a first tag label containing alphanumeric text created and inputted by a user of the client device; modifying, using a controller device, a selected first one of the tags of the metadata in a first of the digital files to include the first tag label; receiving, via the user interface device or another user interface device, an instruction to search for all of the digital files having at least the first tag label; responsive to receiving the instruction, automatically searching for all of the digital files having at least the first tag label; and displaying, on a video display device associated with the client device, a first indication of the first tag label.

Techniques for media capture based on media specifications are described and are implementable to enable media content to be captured and/or obtained in compliance with particular media specifications. The described implementations, for example, utilize specified media specifications (e.g., media constraints) to be utilized as part of a media capture process. For instance, default media capture settings of a media capture device are modified to enable the media capture device to capture an instance of media content that complies with specific media specifications.

Disclosed is a system to provide information associated with a user device from a server to the user device without disclosing the association to the server. Data structures, created at the server, contain information such as information about restaurants, mechanics, medical conditions, etc. The server creates bundles including two or more data structures containing disparate information, and a unique identifier for each bundle. The server creates a table of contents indicating the unique identifier of a bundle and the information contained in the bundle and sends the table of contents to the device. The server receives the unique identifier of the bundle and provides the bundle having the unique identifier to the device. While the bundle contains the information associated with the user device, because the bundle contains disparate information. the server does not know which information is associated with the user device.

An example method performed by a processing system includes retrieving a digital model of a media element from a database storing a plurality of media elements, wherein the media element is to be inserted into a scene of an audiovisual media, rendering the media element in the scene of the audiovisual media, based on the digital model of the media element and on metadata associated with the digital model to produce a rendered media element, wherein the metadata describes a characteristic of the media element and a limit on the characteristic, and inserting the rendered media element into the scene of the audiovisual media.

An apparatus generates an image file having a structure including a first region and a second region, the first region storing a plurality of instances of image data and the second region storing metadata pertaining to the plurality of instances of image data. The metadata includes synchronous group information that groups image data shot synchronously with respect to time, the synchronous group information indicating image data, among the plurality of instances of image data, belonging to a group created by the grouping, and indicator information that indicates an indicator of grouping for the group indicated by the synchronous group information. The apparatus configures the synchronous group information and the indicator information based on the shooting information, and generates the image file storing the plurality of instances of image data, and the configured synchronous group information and the configured indicator information.

Mobile phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some aspects relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others concern user interface improvements. Other aspects relate to imaging architectures, in which a mobile phone's image sensor is one in a chain of stages that successively act on packetized instructions/data, to capture and later process imagery. Still other aspects relate to distribution of processing tasks between the mobile device and remote resources (“the cloud”). Elemental image processing (e.g., simple filtering and edge detection) can be performed on the mobile phone, while other operations can be referred out to remote service providers. The remote service providers can be selected using techniques such as reverse auctions, through which they compete for processing tasks. A great number of other features and arrangements are also detailed.
