Investigations of Digital Image Analysis and Enhancements of GLORIA acoustic Imagery

Abstract

The U.S. Navy is interested in improving underwater mapping and interpretation technologies for bottom and subbottom segmentation and classification, as well as feature extraction, etc. NORDA's Mapping, Charting, and Geodesy Division was tasked to analyze imagery from the U.S. Geological Survey's (USGS) Exclusive Economic Zone Survey Experiment. Digitally mosaicked GLORIA acoustic imagery were analyzed as a zero-order model for the acoustic imagery sensor, TAMU2. Multiple image analysis techniques, were applied to the data set. Information gained from the analyses will be used in the exploration of TAMU2 imagery and bathymetry, when available, for U.S. Navy applications. This report describes the systems, the USGS experiment, and the methods used to analyze the GLORIA data. Geological interpretations are provided. TAMU2 is a towed, multispectral, bilateral imaging sonar capable of simultaneously generating, in real time, ship-speed corrected and slant-range-corrected acoustic backscatter images.
