Paper Abstract

High-resolution sidescan sonars are often used in underwater warfare for large-area surveys of the seafloor in the search for sea mines. Much effort has gone toward the automatic detection of sea mines. In its more advanced forms, such auto-detection entails pattern recognition: the automatic assignment of class labels (target/non-target) to signatures according to their distinctive features. This paper demonstrates a texture-based feature for automatically discriminating between man-made and natural objects. Real sonar data is used, and the demonstration includes performance estimates in the form of the receiver-operator characteristic (ROC) curves necessary (though often omitted) for evaluating detectors for operational use. The merits of redefining the allowable automatic responses-from the classes of mine targets ultimately sought, to the class of man-made objects more generally-are reviewed from both the pattern-recognition and operational perspectives.
