Abstract: Multisampling techniques provide temporal as well as spatial antialiasing. Coverage for a primitive is determined at multiple sample locations for a pixel. In one embodiment, coverage is determined using boundary equations representing a boundary surface of the primitive in a three-dimensional space-time. A shading value for the primitive is computed for the pixel and stored for each coverage sample location of the pixel that is covered by the primitive. The sample locations are distributed in both space and time, and multiple sample locations share a single shading computation. The multisampling techniques are extendable to other dimensions that correspond to other image attributes.

Abstract: Systems, methods, and computer readable media for implementing reentrant compositing window manager applications are described. In general, techniques are disclosed for using a second application to composite portions of hierarchically structured objects and the window manager to composite certain other portions of the same object. More particularly, a window manager application may be used to composite objects of a first type (e.g., application backing store bitmaps) and then call or invoke a second application to composite objects of a second type (e.g., hierarchically structured objects). The second type of object includes information (e.g., a reference) of the composite window manager's output buffer at the time the second application was invoked.

Abstract: Generating a composite geo-referenced panoramic field of view image of a geographic area is provided. Geodetic coordinates are generated for each of a plurality of pixels in a digital image capturing the geographic area based on a corrected amount of image distortion in each line of pixels in the plurality of pixels in the digital image. Each of the plurality of pixels in the digital image with the calculated geodetic coordinates is mapped to a geo-referenced map corresponding to the geographic area based on the calculated geodetic coordinates of each pixel. The composite geo-referenced panoramic field of view image of the geographic area is generated based on the mapping of each of the plurality of pixels in the digital image with the calculated geodetic coordinates to the geo-referenced map corresponding to the geographic area captured in the digital image.

Abstract: A method for determining the afterimage level of a display is used for solving the problem in the conventional technology that the accuracy is very low as the afterimage level of the display can only be determined by human-eye observation. The method comprises: determining a brightness variation index and an area index of an afterimage displayed by the display device after an afterimage test; and determining the afterimage level of the display device according to the determined brightness variation index and the determined area index. Because both the brightness variation index and the area index of the afterimage can be determined objectively, the means of human-eye subjective observation is not required any more and the afterimage level of the display can be determined objectively, and hence the accuracy of determining the afterimage level of the display can be improved.

Abstract: A method of creation of a virtual three dimensional image to enable its reproduction on at least one planar substrate includes creating a virtual three dimensional space that includes a ground plane. A virtual model of an object is merged into the virtual three dimensional space and located at a desired position on the ground plane. A first virtual camera is placed at a first position in the virtual three dimensional space. Virtual lighting is added to the virtual three dimensional space to create shadows of the virtual model on at least the ground plane. The first virtual camera is used for rendering of the virtual model and the shadows to obtain a rendered image. The virtual model is removed and the rendered image is projected onto the ground plane.

Abstract: Embodiments of the invention include a method, a system, and a mobile device that incorporate augmented reality technology into land surveying, 3D laser scanning, and digital modeling processes. By incorporating the augmented reality technology, a 3D digital model of internal elements concealed behind an external element can be visualized on a live view, aligned to the orientation and scale of the scene displayed on the mobile device. In an embodiment, a marker can be placed at a predetermined set of coordinates on the external element, determined by surveying equipment. The 3D digital model of the internal elements can be retrieved by the mobile device and overlaid in relation to the marker position, orientation, and size so that it is seen at a calculated distance in depth behind the external element as they would exist hidden behind the external element in the real environment.

Abstract: A method of distributing map data from a map server to a wireless communications device entails generating a bitmap array representative of the vector map data for a given zoom level, computing attributes of the bitmap array to determine which map features to retain and which map features to suppress, and then transmitting to the wireless device only the map data for the map features to be retained. By counting the number of bitmap cells representing a polygonal map feature such as a park, lake, or island, the approximate area is quickly estimated. If the area falls below a threshold, the map data for the small polygon is discarded. Similarly, if a polyline map feature overlaps (or is too proximate to) another polyline map feature, one of the polyline map features is discarded. The map data actually transmitted is thus reduced, thereby economizing bandwidth without unduly sacrificing map detail.

Abstract: The technology provides contextual personal information by a mixed reality display device system being worn by a user. A user inputs person selection criteria, and the display system sends a request for data identifying at least one person in a location of the user who satisfy the person selection criteria to a cloud based application with access to user profile data for multiple users. Upon receiving data identifying the at least one person, the display system outputs data identifying the person if he or she is within the field of view. An identifier and a position indicator of the person in the location is output if not. Directional sensors on the display device may also be used for determining a position of the person. Cloud based executing software can identify and track the positions of people based on image and non-image data from display devices in the location.

Abstract: A system and method for digital hair coloring is described. A starting image of a subject including a hair region is obtained. At least one foreground selection of the starting image is obtained, the foreground selection including a portion of the hair region. At least one background selection of the starting image excluding the hair region is obtained. A matte defining a calculated foreground area of the starting image is calculated based on the foreground selection and the background selection. A target color distribution based on a target hair color is obtained. A color image is generated by applying a color transformation based on the target color distribution to at least the calculated foreground area of the starting image. An output image is generated from the colored image and the starting image.

Abstract: A novel algorithmic framework is presented for the simulation of hyperelastic soft tissues that drastically improves each aspect discussed above compared to existing techniques. The approach is robust to large deformation (even inverted configurations) and extremely stable by virtue of careful treatment of linearization. Additionally, a new multigrid approach is presented to efficiently support hundreds of thousands of degrees of freedom (rather than the few thousands typical of existing techniques) in a production environment. Furthermore, these performance and robustness improvements are guaranteed in the presence of both collision and quasistatic/implicit time stepping techniques. The result is a significant advance in the applicability of hyperelastic simulation to skeleton driven character skinning.

Abstract: A data access method applicable to a storage apparatus for reducing or eliminating an image tearing effect includes defining at least one write check point; comparing an actual write speed for writing data into the storage apparatus with a predetermined write speed at the write check point; and adjusting the actual write speed when a difference between the actual write speed and the predetermined write speed is larger than a predetermined value, for adaptively reducing the difference to be smaller than or equal to the predetermined value.

Abstract: An image of an environment including an object (i.e., object in reality, physical object) can be captured and be displayed by a computing device. The size of an image representation of the object can be determined. Information about a physical size of the object and about a distance between the computing device and the object in the environment can be obtained/determined. A comparison of the size of the image representation of the object and the physical size of the object can be used to calculate a scale for converting between an actual size of a real-world item and a size of the item as displayed. The information about the distance can optionally be used to determine/adjust/modify the scale. A virtual article depicting/representing a real-world article/item/object (i.e., real-world correspondence) can be displayed with the captured image. The virtual article displayed can be scaled to an appropriate size using the scale.
