“New breakthroughs have been made in maritime intelligent monitoring technology, and researchers have proposed an improved nuclear correlation filter based ship target tracking algorithm to address the problem of ship target tracking at sea. This algorithm effectively improves tracking accuracy and speed by introducing ship target tracking critical probability, Kalman filtering module, and target tracking anomaly handling module. The experiment shows that the algorithm performs well in complex sea conditions, meeting the requirements of accuracy, real-time performance, and applicability for tracking maritime targets.”
