whitepaper Using Aerial Photographs for Improved Mobile AR Annotation2006-12-03 University of California
  This paper presents a mobile augmented reality system for outdoor annotation of the real world. To reduce user burden, it uses aerial photographs in addition to the wearable system's usual data sources (position, orientation, camera and user input). This allows the user to accurately annotate 3D features with only a few simple interactions from a single position by aligning features in both their first-person viewpoint and in the aerial view. This paper examines three types of aerial photograph features - corners, edges, and regions - that are suitable for a wide variety of useful mobile augmented reality applications, and are easily visible on aerial photographs.

whitepaper Computer-Aided Detection in Echocardiography: Technical Approach for Learned Pattern Recognition2006-07-01 siemens
  The reliable delineation of the Left Ventricle (LV) for robust quantification requires years of clinical experience and expertise by echocardiographers and sonographers. Even with acceptable image quality, issues such as trabeculations of the myocardium, fast-moving valves, chordi and papillary muscles, all contribute to the challenges associated with delineation of the LV. Technical issues, such as the fact that a 2D plane is acquired on a twisting 3D object, make this problem even more difficult. Limited success has been achieved in automated quantification based on LV delineation with methods that simply look for a border between black and white structures in an image.

whitepaper The Data Quality Business Case: Projecting Return on Investment2006-06-01 INFORMATICA
  The need for high quality data permeates most information-centric programs, whether they depend on transactional, operational, or analytic applications. This white paper outlines the importance of maintaining data integrity, describes the data quality improvement process, and explores how data quality software solutions fit into that process.

whitepaper Ask Not for Whom the Visualization Is Rendered; It Is Rendered for Thee2006-04-27 Microsoft
  One frequent challenge with many information visualizations is a sense of purposelessness: while the visualization may lead to "New insight", it is often ambiguous what that new insight, in turn, leads to. Although the attempt to justify the visualization is derided as "The obligatory implications paragraph," it also represents the need which drives the visualization. This paper argues that one needs to carefully consider who is to use social visualization, and for what; and discuss some special issues that come into play with the interaction of human perception, social participation, and visualization.   
whitepaper Viewing and Organizing Camera RAW Images in Windows XP: Using the Microsoft RAW Image Thumbnailer and Viewer2005-12-01 Microsoft
  Use of RAW image capture is preferred by many serious-minded photographers to preserve all the subtle color and detail possible from digital cameras. However, until now it has been impossible to view thumbnails and previews for RAW images in Microsoft Windows without use of special software. The Microsoft RAW Image Thumb-nailer and Viewer provides thumbnails, previews, printing, and meta-data display for RAW images from supported Canon and Nikon digital cameras on Windows XP. This tool, which is licensed at no cost by Microsoft, enables digital photographers to organize and work with RAW files within Windows in much the same way as with JPEG images. No more "Guessing" which image is which.

whitepaper Interactive Tools for Virtual X-Ray Vision in Mobile Augmented Reality2005-11-30 University of California
  This paper presents a set of interactive tools designed to give users Virtual X-Ray vision. These tools address a common problem in depicting occluded infrastructure: either too much information is displayed, confusing users, or too little information is displayed, depriving users of important depth cues. Four tools are presented: The Tunnel Tool and Room Selector Tool directly augment the user's view of the environment, allowing them to explore the scene in direct, first person view. The Room in Miniature Tool allows the user to select and interact with a room from a third person perspective, allowing users to view the contents of the room from points of view that would normally be difficult or impossible to achieve.
