Abstract:

The authors have investigated image analysis methods for tracking moving objects in marine environments. They focused on information-theoretic approaches that compare image regions of interest with the statistical models of the objects to be tracked. They evaluated the tracking performance of mean-shift and block-matching algorithms on videos of waterways. It is challenging to track naval vessels in these videos due to glare from the water surface, up and down movements of vessels, and occlusions. They found that the performance of the mean-shift tracking approach was superior to the performance of the block-matching approach in videos with low contrast between the naval vessels to be tracked and the surrounding water surface, and where the scale and orientation of the vessels changed.
