Accurate estimation of detection/classification performance for sidescan sonar systems in Mine Counter-Measure (MCM) applications is important for informing mission tactics and adapting autonomous behaviors. The approach presented in this paper assumes that detection/classification performance can be estimated solely from historical data collected from similar surveys. This paper introduces an algorithm...
This paper describes the use of local sea-floor characteristics to train a neural network to remove false alarms from an Automatic Target Recognition (ATR) algorithm. We demonstrate that this reduces the Probability of False Alarm (PFA) in difficult areas without impacting the Probability of Detection (PD) in flat areas. The sea-floor characteristics are calculated from the texture and appearance...
This paper presents a model-based, filter response algorithm for Automatic Target Recognition (ATR) in Sidescan Sonar (SSS). The filters are created from the projection of a large set of generating boxes. The first and second-order statistics over the highlight and shadow regions of the projected boxes form a feature vector for each pixel in the image. The algorithm selects the features which best...
