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.

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.

Parameterized Extraction of Tiles in Multilevel Gigapixel Images
2021 12th International Symposium on Image and Signal Processing and Analysis (ISPA), 2021In many image domains using multilevel gigapixel images, each image level may reveal different information. E.g., a histological image will reveal specific diagnostic information at different resolutions. By incorporating all levels in deep learning models, the accuracy can be improved.

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 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 ...
