Detection of mines on the seafloor is most accurately performed by a human operator. However, it is a difficult task for machine vision methods. In addition, mine detection calls for high accuracy detection because of the high-risk nature of the problem. The advancements in the capabilities of sonar imaging and autonomous underwater vehicles has led to research using machine learning techniques and well known computer vision features (Barngrover et al., IEEE J. Ocean Eng. (2015), [1]). Non-linear classifiers such as Haar-like feature classifiers have shown good potential in extracting complex spatial and temporal patterns from noisy multidirectional series of sonar imagery, however this approach is dependent on specific sonar illumination methods and does not account for amount of lighting or soil type variation in training and test images. In this paper, we report on the preliminary methods and results of applying a non-linear classification method, convolutional neural networks (CNN) to mine detection in noisy sonar imagery. The advantage of this method is that it can learn more abstract and complex features in the input space, leading to a lower false-positive and higher true positive rates. CNNs routinely outperform other methods in similar machine vision tasks (Deng and Yu, Found. Trends Signal Process. 7, 197–387 (2013), [2]). We used a simple CNN architecture trained to distinguish mine-like objects from background clutter with up to 99% accuracy.
