High-Flux Count-Free Single-Photon 3D Cameras
Kaustubh Sadekar, Vivek K Goyal, David Maier +1
Single-photon cameras based on single-photon avalanche diode (SPAD) technology are gaining popularity for 3D sensing, thanks to their extreme sensitivity and time resolution. There…
RASP: Revisiting 3D Anamorphic Art for Shadow-Guided Packing of Irregular Objects
Soumyaratna Debnath, Ashish Tiwari, Kaustubh Sadekar +1
Recent advancements in learning-based methods have opened new avenues for exploring and interpreting art forms, such as shadow art, origami, and sketch art, through computational m…
Single-Photon 3D Imaging with Equi-Depth Photon Histograms
Kaustubh Sadekar, David Maier, Atul Ingle
Single-photon cameras present a promising avenue for high-resolution 3D imaging. They have ultra-high sensitivity -- down to individual photons -- and can record photon arrival tim…
TreeGCN-ED: Encoding Point Cloud using a Tree-Structured Graph Network
Prajwal Singh, Kaustubh Sadekar, Shanmuganathan Raman
Point cloud is one of the widely used techniques for representing and storing 3D geometric data. In the past several methods have been proposed for processing point clouds. Methods…
Shadow Art Revisited: A Differentiable Rendering Based Approach
Kaustubh Sadekar, Ashish Tiwari, Shanmuganathan Raman
While recent learning based methods have been observed to be superior for several vision-related applications, their potential in generating artistic effects has not been explored…
LS-HDIB: A Large Scale Handwritten Document Image Binarization Dataset
Kaustubh Sadekar, Ashish Tiwari, Prajwal Singh +1
Handwritten document image binarization is challenging due to high variability in the written content and complex background attributes such as page style, paper quality, stains, s…
