Detecting subsurface drainage pipes using a fully convolutional network with optical images

  • Subsurface drainage pipes are identified based on a fully convolutional network

  • Higher albedo directly above drainage pipes than elsewhere is used for detections

  • The proposed approach achieves robust drain pipe detections than conventional methods
