Abstract: A graphics processing system configured to track per-tile event counts in a tile-based architecture. A tiling unit in the graphics processing system is configured to cause a screen-space pipeline to load a count value associated with a first cache tile into a count memory and to cause the screen-space pipeline to process a first set of primitives that intersect the first cache tile. The tiling unit is further configured to cause the screen-space pipeline to store a second count value in a report memory location. The tiling unit is also configured to cause the screen-space pipeline to process a second set of primitives that intersect the first cache tile and to cause the screen-space pipeline to store a third count value in the first accumulating memory. Conditional rendering operations may be performed on a per-cache tile basis, based on the per-tile event count.

Abstract: A synthetic acceleration shape bound primitives composing a 3-D scene, and is defined using a group of fundamental shapes arranged to bound the primitives, and for which intersection results for group members yield an ultimate intersection testing result for the synthetic shape, using a logical operator. For example, two or more spheres are used to bound an object so that each of the spheres is larger than a minimum necessary to bound the object, and a volume defined by an intersection between the shapes defines a smaller volume in which the object is bounded. A ray is found to potentially intersect the object only if it intersects both spheres. In another example, an element may be defined by a volumetric union of component elements. Indicators can determine how groups of shapes should be interpreted. Synthetic shapes can be treated as a single element in a graph or hierarchical arrangement of acceleration elements.

Abstract: Techniques are described to configure a cache line structure based on attributes of a draw call and access direction of a texture. Attributes of textures (e.g., texture format and filter type), samplers, and shaders used by the draw call can be considered to determine the line size of a cache. Access direction can be considered to reduce the number of lines that are used to store texels required by a sample request.

Three-dimensional images are respectively modulated in coordination with the predetermined angularly-responsive reflective surface function to define a programmable mirror with a programmable deflection angle.

Abstract: Enhancing image dynamic range is described. An input video signal that is represented in a first color space with a first color gamut, which is related to a first dynamic range, is converted to a video signal that is represented in a second color space with a second color gamut. The second color space is associated with a second dynamic range. At least two (e.g., three) color-related components of the converted video signal are mapped over the second dynamic range.

Abstract: Techniques are disclosed for generating stereoscopic images. The techniques include receiving a first image frame associated with a first eye, and receiving a first depth frame associated with the first eye. The techniques further include reprojecting the first image frame based on the first depth frame to create a second image frame associated with a second eye. The techniques further include identifying a first pixel in the second image frame that remains unwritten as a result of reprojecting the first image frame, and determining a value for the first pixel based on a corresponding pixel in a prior image frame associated with the second eye. One advantage of the disclosed techniques is that DIBR reprojected image frames have a more realistic appearance where gaps are filled using pixels from a prior image for the same eye.

Abstract: Techniques for linking and browsing media on a television (TV) are provided. A selected program, which is associated with a channel of the TV, is detected and additional content, which is associated with that channel and/or the selected program, is dynamically acquired from one or more external sources. The additional content is formatted as links and simultaneously presented within a display of the TV along with the selected program that continues to play on the TV. Furthermore, activation of any link results in the additional content being dynamically acquired and presented within the display.

The node moving unit repeatedly performs at least once the node moving process until a predesignated condition is satisfied.

Abstract: Techniques are disclosed for rendering complex artwork using tile-based caching. The artwork is divided into one or more sets of separately rendered tiles. Each tile is progressively rendered at a particular scale level and stored in a cache. When the clip region or scale level is changed by the user, tiles in the cache that provide a so-called best rendering of the artwork in the clip region at the requested scale or zoom level are selected. The selected tiles can be displayed in the clip region while the artwork is rendered at the requested scale level. The best rendering includes the tile or tiles that are more completely rendered than other tiles in the cache, or if multiple tiles are as completely rendered as others, the best rendering includes the tile or tiles that are rendered at a scale level closest to the requested scale level.

Abstract: Early depth test stages of a graphics processing pipeline broadcast information about fragments having conditional discard tests associated with them and that pass those early depth tests to other stages in the pipeline. The other stages in the pipeline use the early depth test pass information to determine if the processing of any fragments that they are currently processing can be slowed down. If a fragment that triggered the slowing down of the processing of fragments that are already in the pipeline passes all the conditional discard tests it is to be subjected to, a signal that triggers stopping of the processing of the fragments whose processing it had previously slowed down is sent. If the fragment fails a conditional discard test it is to be subjected to, a signal triggering the reviving of the processing of the fragments whose processing it had previously slowed down is sent.

In the invention, a step of initializing a liquid crystal display (LCD) by a kernel is eliminated, and an LCD controller is reinitialized after the waiting information data in a bootloader display memory is copied to the display memory of the kernel, therefore, the LCD can directly read the waiting information data in the display memory of the kernel according to a display memory first address in the LCD controller. The waiting information data in the bootloader display memory is copied to the display memory of the kernel in advance, therefore, the displayed content is not changed completely for users.

Abstract: An autonomous pavement assessment system may receive depth data indicative of the depth of pixels that collectively comprise multiple defective areas of pavement. For each defective area, the system may fit a plane to it; generate a histogram that indicates the frequency of its pixels at different depths; dynamically determine a depth noise threshold for it; generate a binary image of it based on its noise threshold; and generate a depth map of it containing only the pixels that have a depth that meets or exceeds its depth noise threshold. The system may prioritize the multiple defective areas for repair and/or generate optimized rehabilitation routes. Crowd sourcing may be used to gather the depth data, as well as location information for each defective area.

Abstract: One embodiment involves receiving selection of a first quadrilateral and a second quadrilateral in an image being edited in an image editing application. An edge of the first quadrilateral may be shared with an edge of the second quadrilateral. In this embodiment, one or more manipulations associated with the first quadrilateral and/or the second quadrilateral may be received. In response to the received manipulation(s), an updated view of the image is generated or otherwise displayed according to one embodiment. The updated view may be based at least in part on the image, the received manipulation(s), and/or one or more constraints. For example, the updated view may be based at least in part on a three-dimensional scene constraint. In embodiments, the updated view is consistent with a three-dimensional scene in the image. In some embodiments, the updated view is generated in real-time or substantially real-time.

Abstract: Systems, methods, and computer storage mediums are provided for correcting the placement of an object on an image. An example method includes providing the image and depth data that describes the depth of the three-dimensional scene captured by the image. The depth data describes at least a distance between a camera that captured the three-dimensional scene and one or more structures in the scene and a geolocation of the camera when the three-dimensional scene was captured. When the object is moved from a first location on the image to a second location on the image, a set of coordinates that describes the second location relative to the image is received. The set of coordinates are then translated into geolocated coordinates that describe a geolocation that corresponds to the second location. The set of coordinate is translated, at least in part, using the depth data associated with the image.
