Research on Marine Target Tracking of Staring Sequence Images Based on Frame Difference and Correlation Filtering

With the rapid development of satellite technology, synthetic aperture radar and optical satellites play an increasingly important role in maritime reconnaissance. Among them, staring satellites in geostationary orbit can obtain more dynamic information than traditional satellites in low orbit, which has important influence on real-time acquisition of ocean situation and mastery of strategic initiative. To improve the efficiency of tracking marine target in staring sequence images, this paper combines the optimized frame difference method with the correlation filtering method, to track ship targets in GF-4 staring satellite image sequence. The result shows that, the study improves the tracking rate of ship targets significantly, and provides reference for target tracking of staring sequence images.
