A Novel Feature Descriptor Invariant to Complex Brightness Changes | 2009-04-06 | 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.

Parallax Photography: Creating 3D Cinematic Effects From Stills | 2009-03-14 | 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.

Photo Repair and 3D Structure From Flatbed Scanners | 2009-02-21 | 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.

Fast, Affordable, Next-Generation Product Development for Small and Medium-Sized Manufacturers | 2009-02-03 | 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.

Progressive Display for Efficient Visualization: Eliminating Sluggishness of Heavy Geometry Data Using Progressive Display | 2009-01-01 | Geometric |
| Progressive display technologies attempt to solve the problem of visualizing large size 3D data, by optimizing the requirement of computing capacities to process and render the data progressively, targeted at the area of interest in the data set. These applications can bring in significant efficiencies in areas like oil & gas, land surveys, and in archeology for artifact scanning which involves a lot of reverse engineering for digital model reconstruction. Progressive display also extends the capabilities of telemedicine applications, by enabling them to handle large 3D image data over remote and wireless mobile devices. The networking capabilities of such applications enable effective collaboration on visualized data over a network.

A Visual Data Mining Methodology to Conduct Seismic Facies Analysis: Part 2 - Application to 3D Seismic Data | 2009-01-01 | Society of Exploration Geophysicists |
| A visual data-mining approach to unsupervised clustering analysis can be an effective tool for visualizing and understanding patterns inherent in seismic data i.e., seismic facies. The unsupervised clustering analysis is completely data-driven, requiring no external information e.g., well logs to guide the seismic-trace classification. The paper demonstrates the application of the visual data-mining approach to seismic facies analysis on a real 3D seismic data volume. The paper selects two stratigraphic intervals, the first including a Devonian pinnacle reef system and the second containing a Jurassic siliciclastic channel system. Both analyses show major stratigraphic features that can be defined in horizon slices or other types of visualization. However, the visual data-mining approach creates seismic facies maps with improved visual detail, distinguishing seismic trace-shape variability in the data.

3D Packaging Architecture Using Paper as a Dielectric Medium | 2008-12-15 | Institute of Electrical and Electronics Engineers |
| Radio Frequency Identification (RFID) can be utilized for the tagging of a wide variety of application. A Planar Inverted F Antenna (PIFA) for real time locating has been designed, built and characterized on paper substrate. In specific the PIFA for tagging of metallic objects such as containers in ports or automotive applications is designed, fabricated, and characterized on a paper substrate. The antenna interconnect, or simply the shorting via A via, was drilled though the paper substrate using laser in one of the corners of the structure and, and is characterized by plotting S parameters. Agreement between simulation and measurements provide the proof of concept that paper is a good candidate for a multilayer low cost substrate.

Research Report: Are 3D Mice a Smart Buy? | 2008-11-26 | Hewlett-Packard (HP) |
| This paper purported to evaluate the anecdotal claims that 3D mice can significantly improve CAD design engineer productivity. Based on a survey of 190 3D mice users, substantial gains of more than 20% are being experienced by CAD design engineers while using 3D mice with their CAD applications. Underlying user interface research supported that 6DoF navigation and simultaneous two-handedness were two key factors leading to their improvements. Finally, it was shown that an investment in 3D mice can have an unusually fast payback - less than a month - leading to the 3D mice are in fact a "Smart Buy".

A Mobile RFID-Based System for Supporting Evacuation of Buildings | 2008-11-25 | University of Udine |
| Natural and man-made disasters present the need to efficiently and effectively evacuate the people occupying the affected buildings. In such situations, people are usually under stress and the use of a location-aware mobile application for giving evacuation instructions in simple and effective ways can be useful to improve users' decision making. This paper proposes a mobile system that gives evacuation instructions by employing an interactive 3D location-aware model of the building. The main focus of the paper is on the solutions and the technologies adopted for determining user's position into the building and for inter-actively visualizing a 3D model of the building augmented with visual evacuation instructions on mobile devices.

MRI Image Processing & Visualization | 2008-11-20 | |
| The client needed to develop a MRI console application supported by various 2D and 3D post-processing tasks such as Image Filters, Maximum Intensity Projection (MIP), Multi Planar Reformat (MPR), Volume Rendering (VR) and many others. To optimize the time to market the client insisted upon usage of a third party library (Cedara) that provided a key set of algorithms required for the processing. BSI's Imaging team implemented the algorithms by designing the complex IAP pipelines using IAP objects. The following 3D functionalities were developed: MIP, MPR, VR, Virtual Endoscopy. The following 2D image processing features were provided: Addition/Subtraction of images, 2D Filter, Diffusion, Perfusion, BSI also implemented several add-on viewport tools for drawing ROIs and performing measurements on the images.
