Automatic Detection and Feature Extraction of Equatorial Plasma Bubbles From All‐Sky Airglow Image Based on Machine Learning

Space Weather, Volume 23, Issue 5, May 2025.
Abstract We developed a deep convolutional neural network‐based program code that automatically detects equatorial plasma bubbles (EPBs), segments EPB morphologies, and then extracts their features (including EPBs' northernmost foot latitudes and zonal drift velocities) from OI 630 nm airglow images.
