Self-Supervised Material and Texture Representation Learning for Remote Sensing Tasks

CVPR 2022oral

Self-supervised learning aims to learn image feature representations without the usage of manually annotated labels. It is often used as a precursor step to obtain useful initial network weights which contribute to faster convergence and superior performance of downstream tasks. While self-supervisi…

Shape From Sky: Polarimetric Normal Recovery Under the Sky

CVPR 2021poster

The sky exhibits a unique spatial polarization pattern by scattering the unpolarized sun light. Just like insects use this unique angular pattern to navigate, we use it to map pixels to directions on the sky. That is, we show that the unique polarization pattern encoded in the polarimetric appearanc…

Teaching Cameras to Feel: Estimating Tactile Physical Properties of Surfaces From Images

ECCV 2020poster

The connection between visual input and tactile sensing is critical for object manipulation tasks such as grasping, pushing, and maneuvering. In this work, we introduce the challenging task of estimating a set of tactile physical properties from visual information. We aim to build a model that learn…
