Acoustical Boundary Location Through Texture Analysis Of Multibeam Bathymetric Sonar Data, Herb Barad, Andrews B. Martinez, Brian S. Bourgeois, Edit J. Kaminsky

Electrical Engineering Faculty Publications

Texture analysis is performed on multibeam sonar signal returns discriminated angularity by beamforming. A collection of fourteen texture features are computed via co-occurrence matrices and data reduction is then performed using a principal components transformation. Acoustical boundaries (boundaries between regions with homogeneous acoustical properties) are evident from the features. Results indicate that seafloor bottom characteristics can be extracted from these texture features.
