| Abstract: The various technologies presented herein relate to identifying manmade
and/or natural features in a radar image. Two radar images (e.g., single
polarization SAR images) can be captured for a common scene. The first
image is captured at a first instance and the second image is captured at
a second instance, whereby the duration between the captures are of
sufficient time such that temporal decorrelation occurs for natural
surfaces in the scene, and only manmade surfaces, e.g., a road, produce
correlated pixels. A LCCD image comprising the correlated and
decorrelated pixels can be generated from the two radar images. A median
image can be generated from a plurality of radar images, whereby any
features in the median image can be identified. A superpixel operation
can be performed on the LCCD image and the median image, thereby enabling
a feature(s) in the LCCD image to be classified. |
