One of the recent innovations in computer engineering has been the development of multicore processors, which are composed of two or more independent cores in a single physical package. Today, many processors, including digital signal processors (DSPs), mobile, graphics, and general-purpose central processing units (CPUs) [1] have a multicore design, driven by the demand of higher performance. Major CPU vendors have changed strategy away from increasing the raw clock rate to adding on-chip support for multithreading by increases in the number of cores; dualand quad-core processors are now commonplace. Signal and image processing programmers can benefit dramatically from these advances in hardware, by modifying single-threaded code to exploit parallelism to run on multiple cores.

This part of ISO/IEC 14496 describes a model for connecting 3D graphics compression tools defined inISO/IEC 14496 to graphics primitives defined in any other standard, specification or *** goal of this part of ISO/IEC 14496 is to specify an architectural model able to accommodate? third-party XML based descriptions of scene graph and graphics primitives with? (potential) binarization tools and with? MPEG-4 3D graphics compression tools specified in ISO/IEC 14496-2, ISO/IEC 14496-11 andISO/IEC *** advantages of such an approach are on the one side the use of powerful compression tools for graphicsand on the other side the generality of graphics primitives representation. Hence, compression toolsdeveloped in ISO/IEC 14496-2, ISO/IEC 14496-11 and ISO/IEC 14496-16 would be applied not only to thescene graph defined by ISO/IEC 14496-11 but to any scene graph definition. The bitstreams obtained whenusing the model are MP4 formatted and contain XML (or binarized XML) for the scene graph and binaryelementary streams for graphics compression (geometry, texture and animation).

A proposed scatterplot design combines two other designs. One, proposed by Edward Tufte, uses the range-frame; the other, advised by William Cleveland, uses the four-scale-line rectangle. The hybrid design aims to present bivariate data with more information than classic scatterplots or Tufte's and Cleveland's designs. It works well for both single and multiple scatterplots, in the latter case offering efficient comparison of the datasets in the plots. [ABSTRACT FROM PUBLISHER]

The Venus (Virtual Exploration of Underwater Sites) project pooled expertise in disciplines including archaeology, underwater exploration, marine robotics and instrumentation, knowledge representation, photogrammetry, virtual reality, and digital data preservation. It resulted in a series of best practices and procedures for collecting, storing, and visualizing underwater-archaeology data. The variety of visualization tools developed on the project were more successful with the general public than with the archaeologists. However, younger archaeologists (for example, PhD students) expressed enthusiasm for these tools.

Most existing depth estimation methods generate an erroneous depth map when a foreground object contains hairy boundaries and this error is very critical in many applications. To solve this problem, a new depth map enhancement method is proposed. The given depth map is enhanced by propagating depth values of the neighbourhood based on an alpha matte. The experiment results show that the boundary of a hairy object is significantly refined by the proposed method.
