River channel segmentation in polarimetric SAR images: Watershed transform combined with average contrast maximisation
作者:
Highlights:
• A new approach to river channel segmentation from polarimetric SAR images.
• It combines the watershed segmentation with average contrast maximisation.
• The over-segmentation is reduced using gradient reconstruction.
• The average segmentation time for an image of 1383 × 821 pixels amounts to 1.73 s.
• The average overlap value index amounts to 90% in the experiments completed.
