Technologies are provided herein for adaptively learning and matching modalities of face images. A face image is obtained and a biometric signature is generated of the face image. The biometric signature is compared with a stored biometric signature obtained from data storage. Differences are determined between the biometric signature and the stored biometric signature and compared with a proximity threshold. As a result of the comparison with the proximity threshold, the identity of the person in the face image may be determined or the face image may be stored in data storage in association with the identity of the person.

Adaptive learning and matching of face modalities

Technologies are provided herein for determining if a face image is of sufficient quality for facial recognition processing. An image that contains a face image is received and analyzed to identify facial features of the face image. Distances between the facial features are determined and dimensions of regions for the facial features are calculated based on those distances. A plurality of regions in the face image are defined based on the calculated dimensions. A combined pixel contrast quality of the face image is then calculated based on a combination of separate pixel contrast qualities for the plurality of regions. The face image is determined to be of sufficient quality for facial recognition processing in response to the combined pixel contrast quality satisfying one or more criteria.

System and method for selecting images for facial recognition processing

Technologies are provided herein for selecting one or more subimages to be processed from a plurality of images received. A subset of images is identified, from the plurality of images received, that include a face image. The face image is assessed to generate assessment information regarding one or more of a size of the face image, a pose of the face in the face image, sharpness of the face image, and contrast quality of the face image. Each aspect of the assessment information is compared with corresponding criteria and, as a result of determining that the assessment information satisfies the criteria, facial recognition processing is performed on the face image.

Method for selecting images in video of faces in the wild

Technologies are provided for assessing liveness of a subject presented to a set of one or more cameras. A first image and a second image depicting a face are captured during a first time period, and a third image and a fourth image depicting the face are captured during a second time period. A first variance in facial appearance is detected between the first depiction of the face and the third depiction of the face, and a second variance in facial appearance is detected between the second depiction of the face and the fourth depiction of the face. A liveliness of a person is verified based on a determination that the first variance in facial appearance corresponds in time to the second variance in facial appearance.

Face liveness detection systems and methods

Technologies are provided for assessing liveness of a subject presented to a set of one or more cameras. A pair of face images captured during a first time period are respectively obtained from a first and a second camera. Information regarding each face image of the pair of face images is compared with each other to determine whether the pair of face images are consistent with each other. A third face image captured during a second time period is obtained from the first camera. A first face image of the pair of face images and the third face image are assessed to determine the presence of a particular variance between the first face image and the third face image. A result is provided regarding liveness of the subject presented based on the presence of the particular variance and the determination of consistency between the pair of face images.

Summarization segments of an encoded video can be efficiently identified, without the need to decode the encoded video to obtain image data, by analyzing encoded-buffer-size deltas, each indicating an encoded-buffer-size difference between a pair of intra-coded frames of an encoded video.

Video-segment identification systems and methods

In a system comprising media files resident on various devices which can interconnect and provide indices of their media library content, an organization method may provide an aggregate view of the media library of all connected devices ordering the media library contents of various connected devices from the point of view of the device from which the view of the aggregate library will be shown. This point-of-access-centric view of the library may be formed by prioritizing one or more of relevance, reliability, or proximity of the connected devices from the perspective of the viewing device.

Device-centric media prioritization systems and methods

Disclosed is a method and apparatus to programmatically determine a home location for a user, to cluster photographs and videos into events and trips relative to the home location, to determine names for the events and trips, to composite stories created from the events and trips, to update the composited stories over time, and to output the composited stories for display.

Composing media stories method and system

In a system comprising media files resident on various devices, devices equipped with media servers can deliver files to devices with media clients for purposes of playback (rendering) and/or storage. Some media servers may be capable of delivering files in various formats and may offer clients delivery format options. Media clients are aware of preferential list of formats that can be supported on a device and can choose from delivery options provided by media servers. Media files are introduced on the devices either via means external to this system or by leveraging system's media servers and media clients to transfer content between devices. When media files are introduced on the devices by means external to this system, media scanners detect such media files and make it available to media servers and thus to the rest of the system.

Metadata-based file-identification systems and methods

Many media playback devices have a secure environment, with media decrypter and decoder components, and an insecure environment, with intermediate media processing components that are not suitable for secure implementation. In the secure environment, secure components decrypt encrypted media and store the clear-form media in secure memory that can only be accessed by secure components. Secure components also generate a media-data 'proxy', which corresponds structurally to the clear-form media, but which does not include actual clear-form media data. The media-data proxy is provided to insecure intermediate components, which manipulate the proxy to perform operations such as de-multiplexing, loss mitigation, and coded frame assembly. The manipulated proxy is returned to the secure environment, where secure components identify structural changes that were made to the proxy and make corresponding structural changes to the clear-form media before decoding the manipulated clear-form media.

Secure media path system and method

A method and computer program product for processing a locally-stored, specific media data file portion to generate a first normalized packetized stream. A remotely-sourced, specific media data stream is processed to generate a second normalized packetized stream. At least a portion of the first normalized packetized stream and at least a portion of the second normalized packetized stream are combined, using a packet loss tolerant stitching algorithm, to generate a loss-compensated media data stream.

System and method for combining media data

A method and computer program product for receiving a plurality of media data file portions on a client electronic device from a remote distribution server computer. Each media data file portion is associated with a media data stream. A user is allowed to select a specific media data file portion for rendering. The specific media data file portion is chosen from the plurality of media data file portions. Upon the user selecting the specific media data file portion, at least a portion of the specific media data file portion is rendered and a specific media data stream associated with the specific media data file portion is obtained from an on-demand media server computer.

System and method for distributing media data

The invention is related to methods and apparatus that efficiently store and read data in a cache for a server system, such as a media server. The cache stores data for file formats of a streamable file format, such as an MPEG-4 file format. Relatively frequently accessed portions of a streamable file format are maintained with long-life links. For example, selected child atoms of sample table atoms of MPEG-4 file formats can be relatively frequently accessed during the streaming of a media presentation. A virtual address space manager for selected child atoms maintains relatively long-life links to pages or segments of data in a cache that hold data corresponding to these child atoms and can advantageously inhibit the release of these segments to enhance a hit rate for the cache and decrease an amount of thrashing, i.e., repeated paging of data to the cache.
