Parameter-Robust Subspace Correction with Multiple Semidefinite Penalties
Subhransu S. Bhattacharjee
Independently weighted semidefinite penalties arise in augmented-Lagrangian and constrained formulations. This paper characterizes when an exact additive subspace-correction precon…
FlatLands: Generative Floormap Completion From a Single Egocentric View
Subhransu S. Bhattacharjee, Dylan Campbell, Rahul Shome
A single egocentric image typically captures only a small portion of the floor, yet a complete metric traversability map of the surroundings would better serve applications such as…
MatterDoor: Sampling Zero-shot Spatio-semantic Priors using Generative Models
Subhransu S. Bhattacharjee, Hao Lu, Dylan Campbell +1
Autonomous robots often view rooms only partially, through a doorway, where the walls and scene structure hide the geometry and task-relevant semantics needed for safe navigation a…
Believing is Seeing: Unobserved Object Detection using Generative Models
Subhransu S. Bhattacharjee, Dylan Campbell, Rahul Shome
Can objects that are not visible in an image -- but are in the vicinity of the camera -- be detected? This study introduces the novel tasks of 2D, 2.5D and 3D unobserved object det…
