High‐resolution photo‐mosaic time‐series imagery for monitoring human use of an artificial reef

open access: yesEcology and Evolution, Volume 6, Issue 19, Page 6963-6968, October 2016., 2016
Successful marine management relies on understanding patterns of human use; however, obtaining data can be difficult and expensive given the widespread and variable nature of activities conducted. We trailed a novel methodology, CSIRO Ruggedized Autonomous Gigapixal System (CRAGS), for time series of high‐resolution photo‐mosaic (HRPM) imagery to ...

A direct comparison of high-speed methods for the numerical Abel transform

open access: yes, 2019
The Abel transform is a mathematical operation that transforms a cylindrically symmetric three-dimensional (3D) object into its two-dimensional (2D) projection. The inverse Abel transform reconstructs the 3D object from the 2D projection. Abel transforms

MEDCnet: A Memory Efficient Approach for Processing High‐Resolution Fundus Images for Diabetic Retinopathy Classification Using CNN

open access: yesInternational 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.

Multiscale 3D displacement field measurement using stereo digital image correlation on a fractal speckle pattern

open access: yesStrain, 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.

Predicting optical coherence tomography-derived diabetic macular edema grades from fundus photographs using deep learning

open access: yes, 2019
Diabetic eye disease is one of the fastest growing causes of preventable blindness. With the advent of anti-VEGF (vascular endothelial growth factor) therapies, it has become increasingly important to detect center-involved diabetic macular edema (ci-DME)
