A method of segmenting regions of an image wherein a number of partitions are determined based on a range of an image histogram in a logarithmic luminance domain. Regions are defined by the partitions. A mean value of each region is calculated by K-means clustering wherein the clustering is initialized, data is assigned and centroids are updated. Anchor points are determined based on the centroids and a weight of each pixel is computed based on the anchor points.

A user interactive video tone mapping method is provided that can be used for the tone reproduction of high dynamic range (HDR) content on low dynamic range (LDR) displays. The method comprises the steps of selecting a frame of a video sequence; providing a user interface for a user to manually apply scribble marks to the frame; manually applying N scribble marks to the frame, N being a whole number of value 1 or in greater; and tone mapping the video sequence responsive to the scribble marks.

A method and system for calibration and compensation of color in a three dimensional display system includes user calibration of individual color channels using a multiplicity of grey screens while viewing with three dimensional glasses. Look-up tables are generated to ease conversion of input pixels to color corrected pixels to pre-distort the color of the pixels being driven by the three dimensional display system. Input pixels are then converted using the look-up tables and color corrected frames are displayed to a user. The pre-distortion effect allows a user to perceive colors in the three dimensional system as intended with the distortions caused by the viewing glasses and other aspects of the three dimensional display system.

A method for toning mapping high dynamic range (HDR) video for display in low dynamic range display comprises accessing the HDR video; producing a luminance information for the individual frames; partitioning different consecutive groups of frames into segments responsive to the luminance information; classifying the segments into static luminance segments and transient luminance segments; producing a tone mapping parameter set for the static luminance segments; producing a tone mapping parameter set for at least one of the transient luminance segments responsive to the tone mapping parameter set of an adjacent static luminance segment; and tone mapping the static luminance segments and transient luminance segments according to the respective tone mapping parameter sets.

A depth acquisition system utilizes at least three sensors with at least one sensor in a non-colinear configuration to increase depth information. This configuration provides both vertical and horizontal depth information to be combined to enhance image quality, especially in three-dimensional image gathering. Vertical sensor pairs aid in determining disparities for horizontal edges and make depth estimations for horizontal edges more accurate.

Various disclosed embodiments include methods and systems for correlating local media uniform resource identifiers (URIs) between a first web browser of a first user device and a second web browser of a second user device. The method comprises establishing a session between the first web browser, the second web browser, and a server. The method comprises performing an action related to a first URI on the first web browser. The method comprises encoding the performed action as a resource description framework (RDF) graph including the first URI and sending the RDF graph to the server. The method comprises translating the received RDF graph to a second RDF graph including a second URI based on a predicate stored in the server. The method comprises sending the second RDF graph to the second browser.

Various disclosed embodiments include methods and apparatus for dynamically synchronizing hypermedia based on Resource Description Framework (RDF). A method for hypermedia synchronization within a session hosted by a server includes establishing a communications link between the server and a first user device during the session, and generating a first identifier associated with a first uniform resource identifier (URI) that identifies first hypermedia. The method includes receiving, at the server, a request from the first user device including a second URI that identifies second hypermedia to be added to the session, and generating synchronization information providing a temporal relationship between the first URI and the second URI, where the synchronization information includes an RDF triple.

A presence calculation method comprising receiving first presence subscription request for a composite service that comprises a service at the node and a plurality of discrete services at one or more child nodes, sending a second presence subscription request to one or more child nodes in response to the first subscription request, receiving one or more response messages that comprise a collection of presence state transition delays corresponding to the child nodes from the child nodes in response to the second subscription request, determining one or more communication delays between the node and the child nodes using the response messages, computing a presence state transition delay for the composite service using the collection of presence state transition delays and the communication delays; and determining a composite presence state using a mapping between the presence state transition delay for the composite service and the composite presence state.
