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 ...

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.

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.

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.

Optomechanical System Development of the AWARE Gigapixel Scale Camera [PDF]
, 2013 Electronic focal plane arrays (FPA) such as CMOS and CCD sensors have dramatically improved to the point that digital cameras have essentially phased out film (except in very niche applications such as hobby photography and cinema).
