Matching Radar and Satellite Images Employing the Hausdorff Distance for Ship Positioning and Trajectory Estimation
(IEEE, 2006)
The paper describes a technique to match satellite and radar images using the Hausdorff distance (HD). Minimization of the average of a truncated array of sorted Hausdorff distances is used to get estimates for the radar ...
