Paper Abstract
Detection of small vessels is a challenging task for navy, coast guard and port authority for security purposes. Vessel
identification is more complex as compared to other object detection because of its variability in shapes, features and
orientations. Current methods for vessel detection are primarily based on segmentation techniques which are not as
efficient and also require different algorithms for visible and infrared images. In this paper, a new vessel detection
technique is proposed employing anomaly detection. The input intensity image is first converted to feature space using
difference of Gaussian filters. Then a detector filter in the form of Mahalanobis distance is applied to the feature points
to detect anomalies whose characteristics are different from their surroundings. Anomalies are detected as bright spots in
both visible and infrared image. The larger the gray value of the pixels the more anomalous they are to be. The detector
output is then post-processed and a binary image is constructed where the boat edges with strong variance relative to the
background are identified along with few outliers from the background. The resultant image is then clustered to identify
the location of the vessel. The main contribution in this paper is developing an algorithm which can reliably detect small
vessels in visible and infrared images. The proposed method is investigated using real-life vessel images and found to
perform excellent in both visible and infrared images with the same system parameters.
