Abstract: An image processing system includes a setting section and an image processing section. The setting section sets a process condition of electrophotographic image formation suited to reading of an information image that represents data by a pattern. The image processing section performs an image process for preventing degradation, in image quality, of an image other than the information image under the process condition set through the setting section.

Abstract: A display generation system that is able to generate display signals for an underlay image with at least one embedded safety pattern and display images for an overlay image. The display generation system and method are able to determine whether there are any anomalies or graphical errors when an overlay display generated by the system or generated by some other system is displayed simultaneously with the underlay image with the embedded safety pattern. The display generation system uses the embedded safety pattern to detect the occurrence of anomalies in the simultaneous display and uses information from its own generated overlay image to detect graphical errors in the simultaneous display. Flight display systems for aircraft can use the display generation system and method of the present invention to display an underlay image depicting geographical scenery in the vicinity of the aircraft while on the ground, during takeoff or in flight.

Abstract: Localization and map building apparatus and method applicable to a mobile robot are provided. In an exemplary embodiment, a map building apparatus extracts a pattern of landmarks of the same kind and adjusts a landmark map using the extracted pattern when generating the landmark map for localization. Accordingly, since the landmark map is adjusted based on the pattern extracted on the basis of location information of each landmark, accuracy of localization and map building of the mobile robot can be improved.

Abstract: Apparatus and systems utilizing fixed point filtering to perform floating point texture filtering. A texture pipe unit consisting of a texture addressing unit, texture cache unit, and texture filter unit accepts texture requests for a specified pixel from a resource and returns formatted bilinear filtered results based on the specific pixel's corresponding four texels. The texture filtering unit consists of a pre-formatter module, interpolator module, accumulator module and a format module. The pre-formatter module accepts texel data in a floating point or fixed point format. However, if the data is in a floating point format the pre-formatter module converts the floating point data into a normalized fixed point data format whereby the interpolator module may perform its bilinear interpolator functions using standardized fixed point systems and apparatus without necessitating the use of floating point arithmetic units.

Abstract: The rendering on a user interface of a potentially complex computerized scene generation system. The user interface includes visual item(s) that have associated data. In addition, another set of visual items may be driven by data provided to input parameters, and may represent elements in the scene. Through user gestures, a user may correlate data items in the data source visual items with the element visual items to thereby automatically populate the element visual items with data, affecting the rendering of the data-driven element visual items. The element visual items might be linked, once again, perhaps through user gestures, to a parent visual item. In so doing, properties of the parent visual item might change and/or input parameters of the element visual items might change. Accordingly, complex visual scenes may be created through potentially quite simple user gestures.

Abstract: The rendering pipeline is divided into multiple components or modules in a scene graph based visual programming environment. Different stages of the rendering pipeline, such as data conversion, transform function, shading, and rendering, are grouped into independent conceptual modules, and each module is implemented by separate nodes in a scene graph. The user may select different nodes belonging to different modules for inclusion into the scene graph to program the rendering pipeline. The visual program is implicitly compiled and run using an application programming interface for hardware acceleration.

Abstract: Methods, systems and computer program products are disclosed for displaying a preview of pixels to be effected by a brush tip area. Input is received for specifying one or more parameters defining a brush tip area. The one or more parameters include a size of the brush tip area. Pixels associated with a canvas in a display window are scanned. The scanned pixels are mapped back into the brush tip area according to a specified transform. A shape of a brush tip taper is calculated to indicate a softness or hardness of an edge of the brush tip area. An output color is composited to the scanned pixels based on the calculated shape of the brush tip taper. A preview representation is displayed of pixels effected by the brush tip area based on the compositing.

The 3D scan data may be generated at a dental office remote from a location at which the augmented reality system is implemented. In one embodiment, the 3D scan data is provided to the augmented reality system as a digital impression.

In an example, a computing device may be configured to determine a feature-based score that may be based on features of the object including geometry of the object. The computing device also may be configured to receive a plurality of sets of images of the object. A number of respective images of each set of images may be based on the feature-based score.

The computing device also may be configured to determine a respective ranking for each set of images based on the respective image-based score; and select a set of images based on the respective ranking.

Abstract: A three dimensional (3D) graphics application programming interface (API) extension provides support for specifying images in a shared exponent format. The shared exponent format is used to represent high dynamic range textures in a compact encoding to reduce the memory footprint needed to store the image data compared with other high dynamic range formats. Image data is encoded to and decoded from the shared exponent format using a pixel processing pipeline. Image data encoded into the shared exponent format can be decoded and used as texture data during rendering.

Abstract: Various types of data can be collected into a data set and related content and/or related concepts across the data in the data set and/or across search histories can be displayed as a visual representation. The related content/concepts can be presented as a function of incremental revealing of relationships. After reviewing the visual representation, a user can customize the data set and relationships by specifically excluding a related data segment. The visual representation can be applied across multiple searches or other obtained data. Through interaction with the visual representation, a user can drill down into common linkages of the data to more narrowly focus on a subset of the data and/or to refocus a search result and/or to provide annotations.
