Structured light (SL)-based depth-sensing technology illuminates the objects with an array of
dots, and backscattered light is monitored to extract three-dimensional information …

Unwanted camera obstruction can severely degrade captured images, including both scene
occluders near the camera and partial occlusions of the camera cover glass. Such …

Imaging systems consist of cameras to encode visual information about the world and
perception models to interpret this encoding. Cameras contain (1) illumination sources,(2) …

Depth sensors have emerged as a cornerstone sensor modality with diverse applications in
personal hand-held devices, robotics, scientific imaging, autonomous vehicles, and more. In …

Stereo matching is close to hitting a half-century of history, yet witnessed a rapid evolution in
the last decade thanks to deep learning. While previous surveys in the late 2010s covered …

Learning-based stereo methods usually require a large scale dataset with depth, however
obtaining accurate depth in the real domain is difficult, but groundtruth depth is readily …

Today's commodity camera systems rely on compound optics to map light originating from
the scene to positions on the sensor where it gets recorded as an image. To record images …

Structured light has proven instrumental in three-dimensional imaging, LiDAR and
holographic light projection. Metasurfaces, comprising subwavelength-sized nanostructures …

Hyperspectral 3D imaging aims to acquire both depth and spectral information of a scene.
However existing methods are either prohibitively expensive and bulky or compromise on …
