Abstract: In an embodiment, a server executes a first query in a semi-structured database to determine a first list of nodes that each include at least one node-specific data entry that satisfies the first query. The server initializes a Bloom filter with the first list of nodes. The server filters a list of candidate nodes for a second query based on the Bloom filter. The server executes, in conjunction with a faceted search procedure of a set of documents in the semi-structured database, a second query that uses the filtered list of candidate nodes as a facet to determine a second list of nodes that each includes one or more node-specific data entries from the facet that satisfy the second query.

Abstract: In an embodiment, search parameters in a series of search queries directed to a target node of a semi-structured database are categorized as frequently recurring parameters. A partial search query template is populated with shortcut information related to the search parameters, and then used to facilitate execution of a new search query that includes the same search parameters. In another embodiment, an index is generated that links search parameters that return intermediate search result values to search result values that are configured to be obtained when a search is conducted on the intermediate search result values. The index can be generated based upon monitoring of actual searches within the semi-structured database, or alternatively based upon an inspection of the semi-structured database itself.

Abstract: In an embodiment, a server indexes, in a label-path indexed database, a first data entry at a first target node with a given node identifier in accordance with a label-path indexing protocol. After determining that a number of paths from the root node to non-root nodes that share the given node identifier exceeds a threshold, the server indexes a second data entry at a second target node with the given node identifier in a flat-indexed database in accordance with a flat indexing protocol. In an alternative embodiment, the server indexes the first data entry redundantly in both the label-path indexed database and the flat-indexed database while the path number does not exceed the threshold. When the path number exceeds the threshold, the second data entry is indexed in the flat-indexed database only.

Abstract: In an embodiment, a server detects a threshold number of search queries for which the same value at a target node for a document in a semi-structured database is returned as a search result. The server caches the value based on the detection. In another embodiment, the server detects a threshold number of search queries that result in values being returned as search results from a target node. The server caches values at the target node based on the detection. In another embodiment, the server records search result heuristics that indicate a degree to which search results are expected from a set of search queries. The server obtains a merge query and establishes an order in which search queries in the merge query are to be executed based on the recorded search result heuristics.

Abstract: The application discloses systems and methods for X-ray scanning for identifying material composition of an object being scanned. The system includes at least one X-ray source for projecting an X-ray beam on the object, where at least a portion of the projected X-ray beam is transmitted through the object, and an array of detectors for measuring energy spectra of the transmitted X-rays. The measured energy spectra are used to determine atomic number of the object for identifying the material composition of the object. The X-ray scanning system may also have an array of collimated high energy backscattered X-ray detectors for measuring the energy spectrum of X-rays scattered by the object at an angle greater than 90 degrees, where the measured energy spectrum is used in conjunction with the transmission energy spectrum to determine atomic numbers of the object for identifying the material composition of the object.

Abstract: Embodiments of the disclosure provide efficient hardware dispatching of concurrent functions in multicore processors, and related processor systems, methods, and computer-readable media. In one embodiment, a first instruction indicating an operation requesting a concurrent transfer of program control is detected in a first hardware thread of a multicore processor. A request for the concurrent transfer of program control is enqueued in a hardware first-in-first-out (FIFO) queue. A second instruction indicating an operation dispatching the request for the concurrent transfer of program control in the hardware FIFO queue is detected in a second hardware thread of the multicore processor. The request for the concurrent transfer of program control is dequeued from the hardware FIFO queue, and the concurrent transfer of program control is executed in the second hardware thread.

The display device also can include a processor that can receive image data, determine a color conversion parameter based on the color temperature, perform color conversion of the image data based on the color conversion parameter, and adjust at least one display element based on the color converted image data to provide a color within the color gamut of the ambient light.

Abstract: A method of representing an amount of image color in a composite image includes the steps of generating at least one additional opacity channel for use in creating the composite image, and compositing at least one graphical object having object color and object capacity, with an image having image opacity and the image color, to create the composite image. The composite image has composite image color and composite image opacity, and the composite image color and composite image opacity are derived from one or more of the object color, the object opacity, the image color and the image opacity. An additional step includes compositing the object opacity with the additional opacity channel to create an updated opacity channel, with the updated opacity channel representing an amount of the image color remaining in the composite image following the compositing of the at least one graphical object with the image.

Abstract: A method of retrieving an image for display is disclosed. The image is stored in a compressed wavelet-based format having blocks encoded substantially independently. Initially, a representation (1300) of the image is provided at a first (low) resolution (1302). The user can then select a portion (1308) of the representation for reproduction at a predetermined, generally a second (higher), resolution. A first set of blocks is then identified (1322) corresponding to the selected portion(1310), which are then retrieved, decompressed and rendered to display. A second set of blocks (associated with the first set of blocks) is then identified (1326–1340), retrieved and decompressed. The rendered first set of blocks is then modified using the decompressed second set and displayed at the predetermined/second resolution.

Abstract: An intuitive graphical user interface (100) for classifying and searching on a plurality of digital images is disclosed. Multiple simultaneous metadata associations and compound searches may be performed, using disclosed methods. Such operations may be performed using simple user actions, which will be familiar to inexperienced or casual computer users who typically want to perform such operations on digital images without a commitment to learning new software or operating paradigms. Metadata is associated with digital images by selecting iconic or thumbnail representations of the images (e.g., 107) and dragging the iconic or thumbnail representations to a destination point to either create a new association for a collection of images or to associate a pre-existing metadata item with the images.

Abstract: A method for rendering or compositing image components, where at least one of the image components has an edge. The edge is rendered or composited a plurality of times, the repetitions being performed with different values of the edge thickness (i.e., the thickness of the line) and with different opacities. This makes it possible to create in this way an opacity gradient or the like, so that the edge may be given a softer and less abrupt appearance, if such is desired.
