Blue Marble: A Method for Visualizing Giga-Pixel Layered Imagery for Tiled Displays
we present a technique for the interactive visualization and interrogation of multi-spectral giga-pixel imagery. Co-registered image layers representing discrete spectral wavelengths and temporal information can be seamlessly displayed and fused. Users can freely pan and zoom, while browsing through the data layers enabling intuitive analysis of the massive, time-varying, multi-spectral, records. A data resource aware display paradigm is introduced that progressively and adaptively loads data as it is needed from remote storage, at the level of resolution supported by the used display device. The result is a highly scalable approach, equally suited for a laptop or ultra-high resolution displays system operating at hundreds of mega-pixels resolution. Different case studies are presented which show the systems utility in the context of geo-referenced and biometric data, as well as analysis cultural artifacts. ()

Wipe-Off: Ultra-High Resolution data manipulation
This project presents a system for visualizing and manipulating multispectral data sets, in particular, in the field of cultural forensics. The data for this project is gathered by scanning artwork using several different imaging modalities, each one useful for identifying different characteristics. Since this data ends up being extremely large, clever techniques need to to be used to both seamlessly display and manipulate with this data in ultra high definition. The presented system enables art historians to have a greater deal of immersion and control when interrogating data sets as well as giving uninformed users the ability to explore and understand these rich data sets.

A view of multi-spectral layers wiped away from the St George data set

This project aims to create ultra-high resolution canvases. The system utilizes a cluster system to allow for the image to be segmented, creating a tiled display. Users can not only view work at over a quarter of billion pixels, but can also manipulate it at a per-pixel basis. By utilizing the graphics processors in parallel the system can instantaneous support massive amounts of data manipulation at twitch interactivity. Work still needs to be done into creating new input devices to the system. ()
