Data are maintained in a distributed computing system that describe a graph. The graph represents relationships among items. The graph has a plurality of vertices that represent the items and a plurality of edges connecting the plurality of vertices. At least one vertex of the plurality of vertices includes a set of label values indicating the at least one vertex's strength of association with a label from a set of labels. The set of labels describe possible characteristics of an item represented by the at least one vertex. At least one edge of the plurality of edges includes a set of label weights for influencing label values that traverse the at least one edge. A label propagation algorithm is executed for a plurality of the vertices in the graph in parallel for a series of synchronized iterations to propagate labels through the graph.

Apparatus and a corresponding method for processing image data are provided. The apparatus has compositing circuitry to generate a composite layer for a frame for display from image data representing plural layers of content within the frame. Plural latency buffers are provided to store at least a portion of the image data representing the plural layers. At least one of the plural latency buffers is larger than at least one other of the plural latency buffers. The compositing circuitry is responsive to at least one characteristic of the plural layers of content to allocate the plural layers to respective latency buffers of the plural latency buffers. Image data information for a layer allocated to the larger latency buffer is available for analysis earlier than that of the layers allocated to the smaller latency buffers and processing efficiencies can then result.

The present invention includes a method for representing a plurality of pre-calculated solutions in radiation therapy that are stored in a database and displayed in a manner controllable by a user. Arrays of DVH curves provide the user with essential information on the ‘quality of a plan’. A DVH diagram is displayed as a main diagram, wherein only one of the solutions is visually represented at a time. By selecting a first starting point on a selected DVH curve as the main diagram, a first straight axis extending through the first starting point is placed. A first region, located around the first starting point and on the first straight axis, is highlighted as a first control region for controllable visualization of the plurality of currently non-displayed solutions stored in the database, the DVH curves of which correspond to the selected DVH curve and intersect the first straight axis.

The subject disclosure is directed towards providing a web application with access to hardware accelerated graphics. A rendering format for a set of video frames is established. A graphics component, which is coupled to a graphics device and associated with an unsupported file type, is identified. The graphics component generates image data compromising the hardware accelerated graphics. When the web application requests a set of video frames, the image data is transformed into the set of video frames in accordance with the format. Then, the set of frames is communicated to a display device.

In one embodiment, techniques are provided for converting a CAD description maintained in a first storage format (e.g., a file-based storage format) of a source repository to a second storage format (e.g., a relational database-based storage format) of an output repository. The techniques may, generate a single, coherent representation from spatially ambiguous “fragments” by generating an acyclic model graph for each graphical view, and then storing models of the acyclic model graph in the second storage format (e.g., the relational database-based storage format). The techniques may further produce a post-conversion CAD description that preserves human-readable names and information relationships related to levels by examining attachment specific copies of level structures (i.e. levels and attached levels) referenced from attachments, and generating from these categories and subcategories in the second storage format (e.g., the relational database-based storage format).

system and method for tracking and annotating objects in a 3D model is disclosed. The method includes receiving a signal feed from a group of sensors including at least one depth sensor, determining a reference signal feed from the signal feed, determining a volumetric representation of at least one object not present in the reference signal feed, assigning a unique volumetric profile to at least one object, and/or storing the unique volumetric profile in an object database. The signal feed may include at least one 3D area of interest. Also, the unique volumetric profile may include a unique volumetric id obtained from a group of attributes. The unique volumetric profile may include at least a unique volumetric position and a unique volumetric centroid. The group of sensors may further include video cameras, thermal, and chemical sensors.

Disclosed is a method for reducing volume of 3D modeling data, including: a first step of selecting a block object in the 3D modeling data, a second step of extracting from the 3D modeling data a target block to be comparable with the block object, a third step of comparing the block object with the target object, and a fourth step of designating the target object as a reference object if the block object and the target object are turned out to be identical with each other as a result of the comparing step.

A method and an apparatus for updating navigation map are disclosed. The method includes: fusing captured three-dimensional (3D) data and two-dimensional data (2D) image data of a street view to generate 3D fused data representing the street view; and updating the navigation map in real time according to the 3D fused data. Thus, the disclosure provides a way to update the navigation map in real time.

Tomographic data representing an imaged three-dimensional object is divided into macro blocks and filtered by visibility and presence in a projected frame of a rendered three-dimensional object to speed rendering of the object. The data are loaded and rendered in parallel for improved speed and capacity.

Implementations generally relate to providing secure digital images. In some implementations, a method includes receiving an input image. The method further includes generating a plurality of partial images derived from the input image. The method further includes displaying the plurality of partial images to a user, where a sum of the partial images provides the input image.
