SeaClass™ is an advanced seabed

segmentation/classification module that

automatically characterizes bottom types based

on statistical properties of sidescan mosaics or

multibeam backscatter imagery. SeaClass is

based on a multi-layer perceptron supervised

neural network. The classification procedure

consists of two stages: a learning stage and a

classification stage. Training is accomplished

by the operator selecting areas in the mosaic of differing bottom type (e.g. sand, rock,

mud, etc.). Training of the classifier neural network then proceeds thru an automated

statistical analysis of the selected samples and a characterization of each type. The

following classification stage is a completely automated process where the entire mosaic

image is segmented into the different classes. Results of the classification are displayed

overlain on the mosaic image with each area colored or optionally with vector/line

boundaries around each area. Output from SeaClass can be the DXF boundary vectors or

a GeoTIFF mosaic image with the displayed color-coded areas.
