INVIGORATE: Interactive Visual Grounding and Grasping in Clutter
Robotics: Science and Systems XVII, 2021 This paper presents INVIGORATE, a robot system that interacts with human through natural language and grasps a specified object in clutter. The objects may occlude, obstruct, or even stack on top of one another. INVIGORATE embodies several challenges: (i) infer the target object among other occluding objects, from input language expressions and RGB ...

Ground Clutter Removal in GPR Surveys
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014 In GPR prospecting, strong reflections due to the background material interface can hinder the detection of localized buried scatterers, especially when the targets are close (in terms of probing wavelength) to the interface. Moreover, signals due to objects located outside the investigated domain and occurring in the observation time window may ...
