Parallel MMS gigapixel imagers
Imaging and Applied Optics 2017 (3D, AIO, COSI, IS, MATH, pcAOP), 2017We 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, 2014Time-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, 2017We 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, 2013In 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, 2021High 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, 2010Robotics 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, 2011Building 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.

Gigapixel imaging with microlens arrays
SPIE Proceedings, 2016A crucial part of the drug discovery process involves imaging the response of thousands of cell cultures to candidate drugs. Quantitative parameters from these “high content screens”, such as protein expression and cell morphology, are extracted from fluorescence and brightfield micrographs.

Feedback stitching for gigapixel video
Journal of Electronic Imaging, 2015Methods of stitching static panoramas are unsuitable for video-rate stitching from camera arrays, because these methods are too computationally intensive for real-time operation and do not take advantage of prior knowledge of camera positions or the coherence between successive frames of a video sequence. We propose feedback stitching, which embeds the
