Hexagon files patent for Zonal Change Detection technique

Hexagon Geospatial has filed a patent for the Image Change Detection technique used in its ERDAS Imagine software package. This new technique automatically compares imagery captured at different times in property change assessment zones.

Users can perform an analysis on a zone-by-zone basis, and find out what changes have occurred in each area. The results are displayed from the highest probability of change to the lowest. This helps the users to easily verify the results and generate a comprehensive report. And even though the tool is aimed at property assessors, the technique can be used in several domains, like natural resource applications, defense and intelligence.
