Journal of Microscopy, Volume 299, Issue 2, Page 155-165, August 2025.Abstract Laser scanning fluorescence microscopy (LSFM) is a widely used imaging method, but image quality is often degraded by noise. Averaging techniques can enhance the signal‐to‐noise ratio (SNR), but while this can improve image quality, excessive frame accumulation can introduce photobleaching and may lead to unnecessarily long acquisition times ...

Zehn Jahre Gaia‐Messungen: Die hochgenaue Kartierung des Himmels
Physik in unserer Zeit, Volume 56, Issue 4, Page 175-183, July 2025.Das astrometrische Weltraumobservatorium Gaia der Europäischen Weltraumorganisation hat die astrometrische Forschung revolutioniert, indem es unter anderem präzise Positionen, Bewegungen und Entfernungen von fast zwei Milliarden Himmelsobjekten gemessen hat. Damit stellt es wertvolle Daten für fast alle Gebiete der Astrophysik bereit. Nach dem Ende der

Gigapixel virtual reality employing live superzoom cameras [PDF]
Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology, 2018 We present a live gigapixel virtual reality system employing a 360° camera, a superzoom camera with a pan-tilt robotic head, and a head-mounted display (HMD). The system is capable of showing on-demand gigapixel-level subregions of 360° videos. Similar systems could be used to have live feed for foveated rendering HMDs.

International Journal of Imaging Systems and Technology, Volume 35, Issue 2, March 2025.ABSTRACT Modern medical imaging equipment can capture very high‐resolution images with detailed features. These high‐resolution images have been used in several domains. Diabetic retinopathy (DR) is a medical condition where increased blood sugar levels of diabetic patients affect the retinal vessels of the eye.

Gigapixel optical microscopy for meteorite characterization [PDF]
Planetary Science, 2013 We present an automated microscopy system for the optical characterization of meteorite thin sections. The system employs focus-stacking and high-dynamic range imaging to facilitate high-contrast and unpolished samples. Images are acquired at ∼385 nm/pixel and automatically stitched together to create a billion-pixel image for a typical ∼1 cm2 thin ...

Wavelet‐Based Feature Extraction for Efficient High‐Resolution Image Classification
Engineering Reports, Volume 7, Issue 2, February 2025.The paper introduces a novel CNN architecture that uses wavelet‐domain inputs for high‐resolution image processing. A wavelet‐domain efficient channel attention module that dynamically focuses on informative wavelet subbands is also presented. The proposed architecture improves classification accuracy while reducing computational complexity.

Strain, Volume 61, Issue 1, February 2025.Abstract Even though the simulations used to predict failure are becoming increasingly predictive, complex multiaxial loading tests are still required to validate the design of structural components in a wide range of industries. Large specimen testing often requires two different scales.

Mosaic, 2014 Una gigapixel image es una imagen digital de mapa de bits que se compone de más de un gigapixel. La creación de estas imágenes tan grandes implica la unión a modo de mosaico de un gran número de capturas fotográficas de alta resolución en una sola que las combina todas. Actualmente tienen especial interés en numerosas disciplinas.

Optical Surface Roughness Estimation Using Artificial Intelligence
Materials and Corrosion, Volume 76, Issue 1, Page 188-196, January 2025.An artificial intelligence (AI) model has been developed using a data set recorded by a laser triangulation scanner and a digital camera. This model is capable of identifying whether blasted steel surfaces are good or bad, and it can also estimate the roughness of these surfaces in the form of the Rz parameter, based on images alone.
