| Abstract: Various embodiments presented herein relate to assigning labels to
segments of a synthetic aperture radar (SAR) image, where the segments
are based upon a speckle-reduced SAR image product. A plurality of SAR
images of a scene are co-registered to form a registered stack of SAR
images. A speckle-reduced SAR image product is generated based upon at
least one registered SAR image in the registered stack of SAR images. The
speckle-reduced SAR image product is segmented into a plurality of
superpixels, and boundaries of the superpixels are applied to the at
least one registered SAR image to form a segmented SAR image. A segment
of the SAR image is then labeled as including or not including a feature,
wherein the label is assigned based upon values of pixels in the segment. |
