Researchers have developed DefocusTrackerAI, a new deep-learning framework for automatically detecting and estimating the positions of defocused particle images. The system utilizes a YOLOv9 architecture, which demonstrated superior performance over Faster R-CNN in detecting astigmatic and non-astigmatic particles across various optical setups and lighting conditions. This framework has shown success in real-world experiments, including fluorescence and shadowgraph data, indicating its potential for applications beyond traditional defocusing particle tracking, such as spray and droplet tracking.
