Background

• Automatic labeling (classification) of geospatial image data

labeling

Problems of Existing Solutions

• Not SMART enough!– Too many parameters to tune– Not accurate enough for complex

scenes– Not robust for different scenes

• Difficult for even experienced image analyst to use!

Our Objectives

• A tool that can be easily used by non-expert users

• A tool that is accurate, robust, and fast for various applications

Our Solutions

• Smart Object based Image Analysis (SmartOBIA)– Label constraint image segmentation– Multi-level object classification– Object model learning with weakly-labeled

and limited sample data

• Patented!
