Image Restoration Algorithm and Propagation Mechanism of Partial Discharge Streamer in Oil–Pressboard Insulation Needle–Plate Electrode

High Voltage, EarlyView.
ABSTRACT Oil–pressboard system is the main insulation form of oil‐immersed transformers, which is prone to partial discharge (PD) and subsequent faults due to contamination or moisture ingress. To investigate the evolutionary characteristics of PD streamers under varying voltages and insulation dimensions, streamer images were captured using a high ...

Exposure Fusion for Dynamic Scenes Combining Retinex Theory and Low-Rank Matrix Completion

IEEE Access, 2019
Exposure fusion (EF) directly generates a low dynamic range (LDR) image with similar image quality to the high dynamic range (HDR) image by combining images of different exposures to overcome the limited dynamic range of common digital cameras.

Seeing Through Scattering With Computational Advances: A Review

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
In scattering media, light scrambles into random speckles and impedes our vision. Unlocking hidden information enables breakthroughs to see behind the opaqueness, inspiring applications in imaging, communication, and encryption. Unlike clear media such as clear water and air, a scattering medium is inhomogeneous, in which propagating photons are ...

Assessing the effectiveness of texture and color enhancement imaging versus white‐light endoscopy in detecting gastrointestinal lesions: A systematic review and meta‐analysis

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Introduction Gastrointestinal cancers account for 26% of cancer incidence and 35% of cancer‐related deaths globally. Early detection is crucial but often limited by white light endoscopy (WLE), which misses subtle lesions. Texture and color enhancement imaging (TXI), introduced in 2020, enhances texture, brightness, and color, addressing WLE's
