Acuity-Driven Gigapixel Visualization

IEEE Transactions on Visualization and Computer Graphics, 2013
We present a framework for acuity-driven visualization of super-high resolution image data on gigapixel displays. Tiled display walls offer a large workspace that can be navigated physically by the user. Based on head tracking information, the physical characteristics of the tiled display and the formulation of visual acuity, we guide an out-of-core ...

Refocusable Gigapixel Panoramas for Immersive VR Experiences

IEEE Transactions on Visualization and Computer Graphics, 2021
There have been significant advances in capturing gigapixel panoramas (GPP). However, solutions for viewing GPPs on head-mounted displays (HMDs) are lagging: an immersive experience requires ultra-fast rendering while directly loading a GPP onto the GPU is infeasible due to limited texture memory capacity.

Annotating gigapixel images

Proceedings of the 21st annual ACM symposium on User interface software and technology, 2008
Panning and zooming interfaces for exploring very large images containing billions of pixels (gigapixel images) have recently appeared on the internet. This paper addresses issues that arise when creating and rendering auditory and textual annotations for such images.

Parallel MMS gigapixel imagers

Imaging and Applied Optics 2017 (3D, AIO, COSI, IS, MATH, pcAOP), 2017
We present a new architecture for monocentric multiscale (MMS) gigapixel imagers. This new architecture parallels multiple MMS imagers together to interleave a continuous wide field-of-view (FOV) coverage, resulting in a more compact system layout.

Gigapixel Whole-Body Microphotography

Frontiers in Optics 2014, 2014
Time-series whole-body microphotography may potentially be used for diagnosing skin disease, telemedicine, surgical field registration, and epidemiological studies. We demonstrate the technology by imaging a volunteer at 0.25 gigapixel resolution in a snapshot.

Gigapixel Panorama Video Loops

ACM Transactions on Graphics, 2017
We present the first technique to create wide-angle, high-resolution looping panoramic videos. Starting with a 2D grid of registered videos acquired on a robotic mount, we formulate a combinatorial optimization to determine for each output pixel the source video and looping parameters that jointly maximize spatiotemporal consistency.

Autofocus for a multiscale gigapixel camera

Applied Optics, 2013
In recent studies, the advanced wide field of view architectures for image reconstruction and exploitation (AWARE) multiscale camera, which is composed of a monocentric objective lens and an array of microcameras, was developed for the realization of snapshot wide field of view and high resolution imaging. This paper describes accelerated autofocus (AF)

Gigapixel Macro Photography of Tree Rings

Tree-Ring Research, 2021
High quality specimen digitization is becoming standard across the sciences, is relevant for curation of natural history collections, and must become a priority for dendrochronology. This paper overviews the enduring role of imaging in dendrochronology, summarizes the potential relevance of gigapixel macro photography of polished specimens, offers a ...

GigaPixels for Science [Education

IEEE Robotics & Automation Magazine, 2010
Robotics technology is changing the way we work, we live, and we play. The GigaPan Project is a robotics education outreach experiment to empower scientists with unprecedented robotic technology for imaging and measure how they document and communicate their discoveries to their peers and to the general public.

Gigapixel synthetic-aperture digital holography

SPIE Proceedings, 2011
Building on the work of Goodman and Lawrence [1], we have extended digital holographic imaging to gigapixel scales with 2-D aperture synthesis. Sub-pixel registration algorithms were required to mosaic together thousands of arrays of data, and phase-error correction algorithms were required to correct for system instabilities.
