Documenting Paintings with Gigapixel Photography [PDF]
Journal of Imaging, 2021 Digital photographic capture of pictorial artworks with gigapixel resolution (around 1000 megapixels or greater) is a novel technique that is beginning to be used by some important international museums as a means of documentation, analysis, and ...

GIGAPIXEL PHOTOGRAPHY FOR HIGH-ACCURACY FACADE DOCUMENTATION: MAPPING THE ORIGINAL LOCATION OF THE FORMA URBIS ROMAE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 The Forma Urbis Romae was a monumental marble map of ancient Rome from the Severan Dynasty. It was originally attached to the interior wall of the Temple of Peace, but through the course of the Middle Ages the marble panels of the map fell off or were ...

Multiscale gigapixel photography
Nature, 2012 Pixel count is the ratio of the solid angle within a camera's field of view to the solid angle covered by a single detector element. Because the size of the smallest resolvable pixel is proportional to aperture diameter and the maximum field of view is scale independent, the diffraction-limited pixel count is proportional to aperture area.

Characterization of spatially varying aberrations for wide field-of-view microscopy. [PDF]
Opt Express, 2013 We describe a simple and robust approach for characterizing the spatially varying pupil aberrations of microscopy systems. In our demonstration with a standard microscope, we derive the location-dependent pupil transfer functions by first capturing ...

Scaling Vision Transformers to Gigapixel Images via Hierarchical Self-Supervised Learning [PDF]
Computer Vision and Pattern Recognition, 2022 Vision Transformers (ViTs) and their multi-scale and hierarchical variations have been successful at capturing image representations but their use has been generally studied for low-resolution images (e.g. 256 × 256, 384 × 384). For gigapixel whole-slide
