Abstract

Although the concept of Regions Of Interest (ROI) is known in video analysis, the ROI extraction problem has been hardly addressed in maritime surveillance, particularly for vessel detection and tracking. A video captured by a maritime surveillance camera may contain irrelevant regions, such as shorelines, bridges and piers. As a result, non-relevant moving objects (e.g. cars moving along the shorelines) can be misleadingly detected by the vessel or ship surveillance system. This paper proposes a robust water region extraction method based on spatiotemporally-oriented energy features in combination with a mean shift clustering algorithm. The method targets not only the conventional RGB surveillance data, but also data from thermal cameras. Experimental
results reveal that the pixel-wise water segmentation recall is 95.23% on average for the RGB images and 94.29% on average for the thermal images, even in the presence of islands or other complex shoreline shapes. The measured average precisions are 93.88% and 95.41% for the RGB and thermal datasets, respectively.
