Abstract: Images may be automatically annotated with place identifiers based on textual metadata associated with the images. The quality of these place identifiers may be scored based on a number of different factors. For example, these annotations may also include confidence and topicality values indicative of the relationships between the place identifier and the text as well as topics of the text of the textual metadata. Images that also have additional location information that includes GPS coordinates or a location specified by a user, may be used to evaluate the quality of a given place identifier, combination of confidence and topicality values, and the overall annotation system. These valuations may, in turn, be used to score the quality of such automatic annotations of other images that do not have such additional location information.

Abstract: Systems and methods for performing shading operations of a three-dimensional model, such as a three-dimensional model of a geographic area, are provided. According to aspects of the present disclosure, shading operations can be performed based on a curvature of the polygon mesh such that smooth surfaces still appear smooth after shading and such that sharp edges still appear sharp after shading. In particular, a curvature-driven normal is used for shading operations that takes into account the local curvature of the polygon mesh. A curvature factor can be obtained for each vertex in the polygon mesh. The curvature factor for each vertex can be a scalar value that describes the degree of local curvature in the mesh polygons connected at the vertex. The curvature-driven normal for each fragment can be determined based on the curvature factors associated with the vertices in the polygon mesh.

Abstract: Methods, systems, and computer-readable media that can perform novel and effective flattening of an image are provided. The flattening can be based on quasiconformal mapping. Such mapping can be used to straighten the main landmark curves with least conformality (angle) distortion. This technique can be referred to as quasiconformal straightening (QCS), and it can provide a canonical and straightforward view of convoluted surfaces. The computation can be based on the holomorphic 1-form method with landmark straightening constraints and quasiconformal optimization.

Abstract: A method for dynamically configuring a graphics pipeline system. The method includes determining an optimal pipeline based on: estimating one or more of memory power consumption and computation power consumption of storing and regenerating intermediate results based on graphics state information and one or more factors; determining granularity for the optimal graphics pipeline configuration based on the graphics state information and the one or more factors; collecting runtime information for primitives from graphics pipeline hardware including factors from tessellation or using graphics state information for determining geometry expansion at an output of one or more shader stages; and determining intermediate results to save from a previous processing pass by comparing memory power consumption needed to save the intermediate results with computation power as well as memory power needed for regenerating the intermediate results in one or more later tile rendering passes.

Abstract: Techniques are disclosed for rendering scene volumes having scene dependent memory requirements. A image plane used to view a three dimensional volume (3D) volume into smaller regions of pixels referred to as buckets. The number of pixels in each bucket may be determined based on an estimated number of samples needed to evaluate a pixel. Samples are computed for each pixels in a given bucket. Should the number of samples exceed the estimated maximum sample count, the bucket is subdivided into sub-buckets, each allocated the same amount of memory as was the original bucket. Dividing a bucket in half effectively doubles both the memory available for rendering the resulting sub-buckets and the maximum number of samples which can be collected for each pixel in the sub-bucket. The process of subdividing a bucket continues until all of the pixels in the original bucket are rendered.

Abstract: The present invention relates to rendering texts in a natural language, namely to manipulating a text in a natural language to generate an image or animation corresponding to this text. The invention is unique mainly in that a sequence of animations is selected, semantically corresponding to a given text. Given a set of animations and a text, the invention makes it possible to compare the sequence of these animations to this text. It is unique in that text templates are used and an optimum sequence of these templates is determined. The idea of the template-based text rendering consists in that the text is manipulated to generate an image or animation with the aid of searching correspondences to a limited number of predefined templates. An animation according to certain style is selected in compliance with each template. Animations are sequentially combined into a single sequence of video images.

Abstract: A hybrid phase-in method mitigates the flicker and rolling artifact based on screen change detection or the combination of screen change detection and image spatial analysis. It applies, for example, to solutions that involve backlight and pixel modulation including global dimming and local dimming. If it is full screen change, then no phase-in is needed and the backlight and pixel change can be applied instantly. If it is partial screen change, then content type and spatial image analysis may be used to decide whether to use phase-in or not. The spatial image analysis concept provides additional useful information besides the image brightness analysis for display backlight power saving solutions to make better tradeoffs between power saving and visual quality.

Abstract: A relationship visualization system displays contextual information for a relationship between two entities of a document management system, such as for a user and a document. The system can receive a request for a relationship visualization from a user, such that the request indicates the user and a document. Then, the system determines, from a multipartite graph, a set of relationship paths coupling entity nodes that correspond to the user and the document. A relationship path can include one or more entity nodes indicating contextual information for the relationship between the user and the document. Then, the system selects a first group of entity nodes from the set of relationship paths to represent the relationship between the user and the document. The system then provides a relationship visualization that displays contextual information from the first group of entity nodes to illustrate the relationship between the user and the document.

Abstract: In a graphics processing pipeline, a processing unit establishes a bounding box around a polygon in order to identify sample points that are covered by the polygon. For a given sample point included within the bounding box, the processing unit constructs a set of lines that intersect at the sample point, where each line in the set of lines is parallel to at least one side of the polygon. When all vertices of the polygon reside on one side of at least one line in the set of lines, the processing unit may reduce the size of the bounding box to exclude the sample point.

A resource is automatically identified from image data captured by at least one capture device of at least one personal A/V apparatus and object reference data.

A property of the resource is also determined from the image data and tracked. A function of a resource may also be stored for determining whether the resource is usable for a task. Responsive to notification criteria for the resource being satisfied, image data related to the resource is displayed on the near-eye AR display.
