Triton SeaClass is an advanced seabed segmentation/classification
module that automatically characterizes bottom types based
on statistical properties of mosaicked sidescan or multibeam
backscatter data. SeaClass is available as an optional module
to both of Triton’s mosaicking and mapping software
packages, Triton Map™ or the new Triton Perspective™.
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 through 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.
Technology
