Capturing and viewing gigapixel images [PDF]

ACM Transactions on Graphics, 2007
We present a system to capture and view "Gigapixel images": very high resolution, high dynamic range, and wide angle imagery consisting of several billion pixels each. A specialized camera mount, in combination with an automated pipeline for alignment, exposure compensation, and stitching, provide the means to acquire Gigapixel images with a standard ...

The problem of segmenting global glomerulosclerosis in gigapixel histopathological images: the borderless glomeruli [PDF]

BMC Nephrology
Background Accurately segmenting glomeruli in kidney whole slide images (WSIs) is essential for advancing automation in renal pathology but remains challenging in cases of global glomerulosclerosis, where Bowman’s capsule boundaries are often unclear ...

Generating dermatopathology reports from gigapixel whole slide images with HistoGPT [PDF]

Nature Communications
Histopathology is the reference standard for diagnosing the presence and nature of many diseases, including cancer. However, analyzing tissue samples under a microscope and summarizing the findings in a comprehensive pathology report is time-consuming ...

Thor: a platform for cell-level investigation of spatial transcriptomics and histology [PDF]

Nature Communications
Spatial transcriptomics links gene expression with tissue morphology, however, current tools often prioritize genomic analysis, lacking integrated image interpretation. To address this, we present Thor, a comprehensive platform for cell-level analysis of

Noble Metals Doping in Lead-Free Double Perovskite Single Crystals: Achieving Near-Infrared to X-ray Broadband Photodetection. [PDF]

Small Sci
This study examines the doping of Cs2AgBiBr6 double perovskite with noble metals (Au3+, Pd2+, and Ir3+). Significant redshifts in the absorption edge enable broadband photodetection from X‐rays to NIR, without abrupt changes in crystal structure. Au doping notably also enhances X‐ray sensitivity.

Combining Ground Based Remote Sensing Tools for Rockfalls Assessment and Monitoring: The Poggio Baldi Landslide Natural Laboratory

Sensors, 2021
Nowadays the use of remote monitoring sensors is a standard practice in landslide characterization and monitoring. In the last decades, technologies such as LiDAR, terrestrial and satellite SAR interferometry (InSAR) and photogrammetry demonstrated a ...

Video enhanced gigapixel panoramas [PDF]

SIGGRAPH Asia 2012 Technical Briefs, 2012
We present a method for embedding video clips within gigapixel scale imagery. The combination of high-resolution imagery and video enables users to pan and zoom across the gigapixel panorama to explore complex scenes with motion. The sparsity of the video content within the gigapixel context introduces several challenges which we overcome by optimizing

Acquisition and Online Display of High‐Resolution Backscattered Electron and X‐Ray Maps of Meteorite Sections

Earth and Space Science, 2021
Analyses of meteorites in thin or thick section begins with a detailed mineralogic/petrologic study of the sample. Backscattered electron and X‐ray imaging in a scanning electron microscope is critical for the characterization and study of the meteorite ...

Gigapixel Computational Imaging [PDF]

2011 IEEE International Conference on Computational Photography (ICCP), 2011
Today, consumer cameras produce photographs with tens of millions of pixels. The recent trend in image sensor resolution seems to suggest that we will soon have cameras with billions of pixels. However, the resolution of any camera is fundamentally limited by geometric aberrations.
