EDGE DETECTION ALGORITHMS IN INTENSITY SAR IMAGES: EMPIRICAL COMPARISON OF PERFORMANCES AND PROPOSED IMPROVEMENTS
Year:2008
Research Areas
  • Processing and signal analysis
Information
Abstract
Different edge-detection algorithms developed for high-speckle SAR images are evaluated and compared. Two evaluation criterions have been selected: (i) quality of the detected edges, specially considering false alarms, edge thickness and level of discontinuities on detected edges. (ii) computational efficiency. Some modifications on the best-perfonnance algorithms regarding edge quality are proposed, at the expense of a certain computational load increase.
