The vehicle surroundings monitoring apparatus which monitors the surroundings of a vehicle by using an image captured by a camera (2R, 2L) mounted on the vehicle, including an object extraction process unit which extracts an image area of the object from the captured image (steps 1 to 6) and an object type determination process unit which determines the object type according to whether the image area of the object extracted by the object extraction process unit includes a first object area of an inverse triangular shape and a second object area located below the first object area and within a predetermined range from the first object area (steps 31 to 36).

Abstract: The invention relates to an editing of a digital document containing an image, a text, a pattern and the like on pages constituting the digital document. In response to an operation for deleting an image positioned in a page, such image is not added to another page but is moved to and displayed in an evacuation area provided independently from the page area. In the evacuation area, such image is displayed together with a serial number of the page in which such image was present originally. Thus the page layout is not destructed in pages other than the page of image deletion, and the user can easily confirm later the image existed in such page.

Abstract: Systems and methods for storing high dynamic range image data in a low dynamic range format may be used to store the high dynamic range image data in less memory. The memory bandwidth needed to access the high dynamic range data is reduced and processing performance may be improved when performance is limited by memory bandwidth. The high dynamic range image data is scaled and compressed into a low dynamic range format for storage in a render target. If the compressed high dynamic range image data contains multiple data samples per pixel, the data may be processed to produce filtered compressed high dynamic range image data with only one sample per pixel. The high dynamic range image may be reconstructed from the low dynamic range format data and further processed as high dynamic range format data for a range of applications.

Abstract: A computer-implemented method, apparatus, and article of manufacture provide the ability to store image data for use in a real-time compositing computer application. A storage tile size is determined based on disk input/output (I/O) hardware testing. A processing tile size is determined based on graphics I/O testing. An image is obtained and processing tiles (of the processing tile size) are mapped over the image. A center of the image is used as a point of origin for the processing tiles. The processing tiles are mapped to storage tiles. The storage tile point of origin is located at a lower left corner of the processing tiles. Each storage tile is configured to contain complete processing tiles that are stored in the storage tiles based on the storage tile size, processing tile size, and the mappings.

Abstract: A computer-implemented method for capturing and processing a series of images captures a first image incorporating a surface having a plurality of markers varying in texture or color to obtain an image representation. A plurality of alignment tracking points, obtained from the plurality of markers, is designated. The plurality of alignment tracking points is utilized in a first image frame to locate a position of a first marker in a second, succeeding image frame. The first marker is reused in the second, succeeding image frame if located. Otherwise, a defined region surrounding the position of the first marker is searched for a second marker matching the first marker in texture or color. The second marker is used in the second, succeeding image if located. Otherwise, a best guess position of the first marker is interpolated by processing translation information of a third marker geometrically interconnected to the first marker.

Abstract: A raster image processing system and method accepts a digital page description as a series of page elements (text, graphics, images, etc.) and creates output video-ready (“flattened”) raster without allocating large amounts of raster memory (arrays of pixels) and without creating a display list of all page elements. This technique improves performance (greater speed with fewer resources consumed) in the typical output process: rendering, image processing, compression, and transmission. The method records each page element in memory in a manner that largely retains the inherent compression of the element description, and fully retains the positional relationships with its neighboring elements. Where an incoming page element overlaps an existing one, the intersections are calculated on the fly, and elements underneath are immediately split, merged, shrunken, or deleted. Each incoming page element is immediately processed and recorded as described above, and then discarded.

Abstract: Embodiments of the invention provide techniques and systems for reducing network traffic in relation to ray-tracing a three dimensional scene. According to one embodiment of the invention, as a ray is traversed through a spatial index, a leaf node may be reached. Subsequent rays that traverse through the spatial index may reach the same leaf node. In contrast to sending information defining a ray issued by the workload manager to a vector throughput engine each time a ray reaches a leaf node, the workload manager may determine if a series of rays reach the same leaf node and send information defining the series of rays to the vector throughput engine. Thus, network traffic may be reduced by sending information which defines a series of rays which are traversed to a common (i.e., the same) leaf node in contrast to sending information each time a ray is traversed to a leaf node.

Abstract: Skin-attached features are placed on a computer generated character by defining a set of placement points on at least a portion of a skin surface of the computer generated character. For each placement point, a radius is defined for the placement point. For each placement point, a density value is determined for the placement point. The density value is a sum of weighted overlaps with neighboring placement points within the radius of the placement point. The weighted overlaps are functions of the radius of the placement point. The number of placement points in the set of placement points is reduced based on the density values.

Abstract: Data conversion circuits and methods of data conversion that enable to keep the continuity in the converted data while reducing a required memory capacity are disclosed. An exemplary conversion circuit includes a LUT that stores representative correction values and an interpolation circuit that generates conversion data by interpolating from representative correction values stored in cells of the LUT that surround an address corresponding to the combination of input signal levels. When the cells that surround the address include a pair of adjacent cells arranged along both sides of a diagonal line of the LUT, the interpolation circuit substitutes one of the representative correction values with a substituted representative correction value that indicates an opposite direction and a same amount of correction as indicated by the other one of the representative correction values stored in the adjacent cells, and then generates the conversion data.

Abstract: A color quantization or re-quantization method is provided that combines two dimensional halftoning with luminance preserving quantization (LPQ) for better perception results of high precision color video quantization. A combination of LPQ and error diffusion, and a combination of LPQ and spatial dithering, is provided. To combine LPQ and spatial dithering, the spatial dithering is regarded as a two-step processing, a mapping and a simple rounding. To combine LPQ and dithering together, a rounding step is replaced by the LPQ algorithm in the combination. Further a method is provided for post-processing which is applicable to both cases to reduce the color perception for grayscale image.

Abstract: The current invention involves new systems and methods for providing variable rasterization performance suited to the size and shape of the primitives being rendered. Portions of pixel tiles that are fully covered by a graphics primitive are encoded and processed by the system as rectangles, rather than expanding to explicit samples. This accelerates the rendering of large primitives without increasing the computation resources used for rasterization. In some embodiments, these fully-covered regions can be rendered compressed without ever expanding into samples.
