A Fast Physics-Based, Environmentally Adaptive Underwater Object Detection Algorithm
"... Abstract—A new algorithm for the detection of underwater man-made objects in sonar imagery is proposed. The algorithm is made extremely fast by employing a cascaded architecture and by exploiting integral-image representations. As a result, the method makes real-time detection of objects of interest ..."

of interest in streaming sonar data collected by an autonomous underwater vehicle feasible. No training data is required because the proposed method is adaptively tailored to the environmental characteristics of the sensed data that is collected in situ. The flexible yet rigorous approach also addresses
Environmental change adaptation for mobile robot navigation
- Journal of the Robotics Society of Japan
, 1998
"... Most of existing robot learning methods have con-sidered the environment where their robots work un-changed, therefore, the robots have to learn from scratch if they encounter new environments. This pa-per proposes a method which adapts robots to envi-ronmental changes by efficiently transferring a ..."

Skill Acquisition and Self-Improvement for Environmental Change Adaptation of Mobile Robot
"... Learning and development are essential processes for an animat to adapt itself to environmental changes so as to accomplish a given task. This paper proposes a single mechanism for learning and self-improvement that results in learning curves similar to the “U-shape” phenomena observed in several ps ..."

A NEW ENVIRONMENTALLY ADAPTIVE CLASSIFICATION ALGORITHM FOR UNDERWATER MINES IN SAS IMAGERY
"... Abstract: A new classification framework is developed to explicitly account for environmental dependence in the underwater mine classification problem. Information describing the local environment of each object is quantified in the form of a novel feature characterizing the seabed; this auxiliary f ..."

Performance Assessment of an Adaptive AUV Survey
"... SHORT ABSTRACT: Traditional underwater surveys employing side-looking sonars are designed by assuming quality data will be collected out to a fixed range. However, environmental factors at sea introduce variability into the coverage actually achieved. To address this issue, the NATO Undersea Researc ..."

On adaptive underwater object detection
- in Proc. Int. Conf. Intell. Robots Syst., 2011
"... Abstract — A new algorithm for the detection of underwater objects in sonar imagery is proposed. One particularly novel component of the algorithm also detects the presence of, and estimates the orientation of, sand ripples. The overall algorithm is made extremely fast by employing a cascaded archit ..."

Sensor-driven online coverage planning for autonomous underwater vehicles
- Mechatronics, IEEE/ASME Transactions on
, 2013
"... Abstract-At present, autonomous underwater vehicle (AUV) mine countermeasure (MCM) surveys are normally pre-planned by operators using ladder or zig-zag paths. Such surveys are conducted with side-looking sonar sensors whose performance is dependant on environmental, target, sensor, and AUV platfor ..."
