whitepaper A Burst of Clean-Energy: How 3D Visualization Can Help to Achieve Commercial Objectives2009-11-01 PlusAnimations
  Explaining how product works, how it could be used, and where it differs from existing technology, is the most difficult part and a decisive element in reaching commercial objectives. A 3D animation can be the solution, since it easily visualizes and explains the use and purpose of something that is hard to explain even in a thousand words. This paper will examine the challenges of presenting products and projects in the renewable energy sector and introduces the many advantages of 3D visualization to help achieve company's commercial objectives.   
whitepaper Improving Depth Perception With Motion Parallax and Its Application in Teleconferencing2009-06-16 Institute of Electrical and Electronics Engineers
  Depth perception, or 3D perception, can add a lot to the feeling of immersiveness in many applications such as 3D TV, 3D teleconferencing, etc. Stereopsis and motion parallax are two of the most important cues for depth perception. Most of the 3D displays today rely on stereopsis to create 3D perception. This paper proposes to improve user's depth perception by tracking their motions and creating motion parallax for the rendered image, which can be done even with legacy displays. Two enabling technologies, face tracking and foreground/background segmentation, are discussed in detail. In particular, the paper proposes an efficient and robust feature based face tracking algorithm that is capable of estimating the face's location and scale accurately.

whitepaper Efficient Modeling & Simulation of Biological Warfare Using Innovative Design of Experiments Methods2009-05-01 SAS Institute
  Innovative Design of Experiments (DOE) methods are used to significantly reduce the number of simulations required to model Biological Warfare (BW) attacks. The methods illustrated are applicable to almost any Modeling and Simulation (M&S) study involving large numbers of variables with many levels. The goal is to create a fast (seconds) surrogate metamodel of the simulation with which to make suitably accurate predictions of the response output for time consuming (hours) simulation trials not yet run. An example is shown that employs DOE methods that can be used when control variables are categorical and/or continuous. The analysis is based on a re-evaluation of data for all 648 possible combinations of settings of six variables in a BW attack case matrix completed for the military.   
whitepaper AMD - Introduction to OpenGL 3.02009-04-27 Advanced Micro Devices
  OpenGL 3.0 is a new open-standard 3D graphics application programming interface specification that gives applications more control over graphics hardware than ever before. OpenGL 3.0 is derived from previous versions of OpenGL, keeping most of the same interfaces and functionality, but adding several new key features. With OpenGL 3.0 comes an updated version of the GL Shading Language, GLSL 1.30. Discussing the individual changes and new features included in OpenGL 3.0 and GLSL 1.30 is beyond the scope of this paper.

whitepaper CACTI 6.0: A Tool to Model Large Caches2009-04-21 Hewlett-Packard (HP)
  Future processors will likely have large on-chip caches with a possibility of dedicating an entire die for on-chip storage in a 3D stacked design. CACTI 6.0 is a significantly enhanced version of the tool that primarily focuses on interconnect design for large caches. In addition to strengthening the existing analytical model of the tool for dominant cache components, CACTI 6.0 includes two major extensions over earlier versions: first, the ability to model Non-Uniform Cache Access (NUCA), and second, the ability to model different types of wires, such as RC based wires with different power, delay, and area characteristics and differential low-swing buses. This paper details the analytical model assumed for the newly added modules along with their validation analysis.

whitepaper Higher Dimensional Blue-Noise Sampling Schemes for Curvelet-Based Seismic Data Recovery2009-04-10 Tsinghua University
  In combination with compressive sensing, a successful reconstruction scheme called Curvelet-based Recovery by Sparsity-promoting Inversion (CRSI) has been developed, and has proven to be useful for seismic data processing. One of the most important issues for CRSI is the sampling scheme, which can greatly affect the quality of reconstruction. Unlike usual regular undersampling, stochastic sampling can convert aliases to easy-to-eliminate noise. Some stochastic sampling methods have been developed for CRSI, e.g. jittered sampling, however most have only been applied to 1D sampling along a line. Seismic datasets are usually higher dimensional and very large, thus it is desirable and often necessary to develop higher dimensional sampling methods to deal with these data.

whitepaper A Novel Feature Descriptor Invariant to Complex Brightness Changes2009-04-06 Institute of Electrical and Electronics Engineers
  This paper describes a novel and robust feature descriptor called Ordinal Spatial Intensity Distribution (OSID) which is invariant to any monotonically increasing brightness changes. Many traditional features are invariant to intensity shift or affine brightness changes but cannot handle more complex nonlinear brightness changes, which often occur due to the nonlinear camera response, variations in capture device parameters, temporal changes in the illumination, and viewpoint-dependent illumination and shadowing. A configuration of spatial patch sub-divisions is defined, and the descriptor is obtained by computing a 2-D histogram in the intensity ordering and spatial sub-division spaces. Extensive experiments show that the proposed descriptor significantly outperforms many state-of-the-art descriptors such as SIFT, GLOH, and PCA-SIFT under complex brightness changes.

whitepaper Parallax Photography: Creating 3D Cinematic Effects From Stills2009-03-14 Microsoft
  This paper presents an approach to convert a small portion of a light field with extracted depth information into a cinematic effect with simulated, smooth camera motion that exhibits a sense of 3D parallax. The paper develops a taxonomy of the cinematic conventions of these effects, distilled from observations of documentary film footage and organized by the number of subjects of interest in the scene. The paper presents an automatic, content-aware approach to apply these cinematic conventions to an input light field. A face detector identifies subjects of interest. The paper then optimizes for a camera path that conforms to a cinematic convention, maximizes apparent parallax, and avoids missing information in the input.

whitepaper Photo Repair and 3D Structure From Flatbed Scanners2009-02-21 Hewlett-Packard (HP)
  The paper introduces a technique that allows 3D information to be captured from a conventional flatbed scanner. The technique requires no hardware modification and allows untrained users to easily capture 3D datasets. Once captured, these datasets can be used for interactive relighting and enhancement of surface detail on physical objects. The paper has also found that the method can be used to scan and repair damaged photographs. Since the only 3D structure on these photographs will typically be surface tears and creases, the method provides an accurate procedure for automatically detecting these flaws without any user intervention. Once detected, automatic techniques, such as infilling and texture synthesis, can be leveraged to seamlessly repair such damaged areas.

whitepaper Fast, Affordable, Next-Generation Product Development for Small and Medium-Sized Manufacturers2009-02-03 Dassault Systèmes
  Good product design isn't about speed, it's about quality. With SolidWorks solutions and an Intel-based Dell Precision Workstation, small and medium-sized companies can now have both. That means knowledge workers can imagine quickly and transform ideas into high-quality products with exceptional speed. It also means that small and medium-sized businesses can be even more effective partners to their large, multinational manufacturing customers, who are increasingly looking to their partners to bolster their product development supply chain.
