Scalable Seams for Gigapixel Panoramas

, 2013
International audienceGigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image.

Plenoptic Imaging and Processing

This open access book delves into the fundamental principles and cutting-edge techniques of plenoptic imaging and processing. Derived from the Latin words "plenus" (meaning "full") and "optic," plenoptic imaging offers a transformative approach to ...

Terapixel Imaging of Cosmological Simulations

, 2018
The increasing size of cosmological simulations has led to the need for new visualization techniques. We focus on smoothed particle hydrodynamic (SPH) simulations run with the GADGET code and describe methods for visually accessing the entire simulation ...

Computational Optical Imaging Systems for Spectroscopy and Wide Field-of-View Gigapixel Photography

, 2013
This dissertation explores computational optical imaging methods to circumvent the physical limitations of classical sensing. An ideal imaging system would maximize resolution in time, spectral bandwidth, three-dimensional object space, and polarization.

Coherent diffractive imaging using table-top sources

, 2017
Lensless microscopy, which is also called coherent diffractive imaging (CDI), is a novel and revolutionary approach to imaging. Compared to lens-based microscopy i.e.

WISE: A Framework for Gigapixel Whole-Slide-Image Lossless Compression

2025 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Whole-Slide Images (WSIs) have revolutionized medical analysis by presenting high-resolution images of the whole tissue slide. Despite avoiding the physical storage of the slides, WSIs require considerable data volume, which makes the storage and maintenance of WSI records costly and unsustainable.

Tradeoffs and Limits in Computational Imaging

, 2011
For centuries, cameras were designed to closely mimic the human visual system. With the rapid increase in computer processing power over the last few decades, researchers in the vision, graphics and optics community have begun to focus their attention on

AISOS: A Reproducible Model for Institution-Wide 3D Imaging

, 2018
In an effort to make emerging 3D and 2D technologies available to a broad range of users, an interdisciplinary group at the University of Minnesota came together to build AISOS, the Advanced Imaging Service for Objects and Spaces.

Developments of Gigapixel Microscopy

, 2014
Fourier ptychographic (FP) imaging is a recently developed technique to get high-resolution high-throughput imaging. FP iteratively stitches together many variably illuminated, low-resolution intensity images in the Fourier space to expand the frequency ...
