The Naval Research Laboratory is developing an Automatic Change Detection and Classification (ACDC) system for the Naval Oceanographic Office to use with sidescan sonar imagery (SSI). The ACDC system will automatically detect seafloor features in SSI; classify, catalog, and cluster the features; and compare them with features previously detected (and stored(More)
A technique is presented to cluster geospatial features on an electronic display and determine a meaningful measure of display clutter. An algorithm previously developed by the Naval Research Laboratory (NRL) to cluster objects in sidescan imagery has been modified to cluster any displayed features in three dimensions: geospatial location (x, y) and color(More)

Intelligent devices, with smart clutter management capabilities, can enhance a user's situational awareness under adverse conditions. Two approaches to assist a user with target detection and clutter analysis are presented, and suggestions on how these tools could be integrated with an electronic chart system are further detailed. The first tool, which can(More)
