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

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)

Refocusable Gigapixel Panoramas for Immersive VR Experiences
IEEE Transactions on Visualization and Computer Graphics, 2021There 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.

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.

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.

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 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.

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.

Multiresolution Analysis on Searching for People in Gigapixel Images
2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE), 2018Digital images can be found in several sizes and they can be easily displayed on a computer screen using algorithms that reduce their dimensions. Recent advances have contributed to the emergence of gigapixel images with a large amount of information. These images can be understood as an image mosaic with multiple single pictures.

Pan-STARRS and Gigapixel Cameras
2006The Pan-STARRS project will undertake repeated surveys of the sky, finding "Killer Asteroids" and everything which moves or blinks, as well as building an unprecedentedly deep and accurate image of the sky. The key technology for this is the next generation of large format cameras, which will offer an order of magnitude improvement in size, speed, and ...
