Volumetric processing of TOPAS underwater acoustic data

This paper describes the application of unsupervised volumetric reconstruction, segmentation and visualization techniques to underwater acoustic data for a 3D seabed analysis. New 3D interpolation and segmentation, methods are introduced and applied to both artificial and real seabed data. In the interpolation, all calculations are done in 3D. For the segmentation, a 3D to 2D simplification is described which yields more accurate results. The results show that the methods can be adequately used for a 3D seabed analysis
