• Overestimation of maximum sonar range (assuming 150m instead of actual 110m) in pre-planned case results in incomplete coverage. • Adaptive method immediately fills in gaps and achieves complete coverage. • Eliminating constraint allows greater coverage faster, but survey takes longer (more tracks and inefficient transit) for complete coverage. 2km x 1km(More)
In this work, we quantify the relationship between synthetic-aperture length (or equivalently, along-track resolution) and seabed segmentation performance experimentally for real synthetic aperture sonar (SAS) imagery. The seabed segmentation algorithm employed uses wavelet-based features, spectral clustering, and a variational Bayesian Gaussian mixture(More)
