Reversing Food Craving Preference Through Multisensory Exposure

no code implementations12 Apr 2022 Avishek Chatterjee, Satyaki Mazumder, Koel Das

Our results asserted the effect of the multisensory food exposure showing statistically significant increase in food craving for negative control post-exposure to disliked food items.

Mo2Cap2: Real-time Mobile 3D Motion Capture with a Cap-mounted Fisheye Camera

no code implementations15 Mar 2018 Weipeng Xu, Avishek Chatterjee, Michael Zollhoefer, Helge Rhodin, Pascal Fua, Hans-Peter Seidel, Christian Theobalt

We tackle these challenges based on a novel lightweight setup that converts a standard baseball cap to a device for high-quality pose estimation based on a single cap-mounted fisheye camera.

LIME: Live Intrinsic Material Estimation

no code implementations CVPR 2018 Abhimitra Meka, Maxim Maximov, Michael Zollhoefer, Avishek Chatterjee, Hans-Peter Seidel, Christian Richardt, Christian Theobalt

We present the first end to end approach for real time material estimation for general object shapes with uniform material that only requires a single color image as input.

MonoPerfCap: Human Performance Capture from Monocular Video

no code implementations7 Aug 2017 Weipeng Xu, Avishek Chatterjee, Michael Zollhöfer, Helge Rhodin, Dushyant Mehta, Hans-Peter Seidel, Christian Theobalt

Reconstruction from monocular video alone is drastically more challenging, since strong occlusions and the inherent depth ambiguity lead to a highly ill-posed reconstruction problem.

Photometric Refinement of Depth Maps for Multi-Albedo Objects

no code implementations CVPR 2015 Avishek Chatterjee, Venu Madhav Govindu

The method of this paper does not require the constant albedo assumption and we believe it is the first work of its kind to handle objects with arbitrary albedo under uncalibrated illumination.

Noise in Structured-Light Stereo Depth Cameras: Modeling and its Applications

no code implementations8 May 2015 Avishek Chatterjee, Venu Madhav Govindu

Depth maps obtained from commercially available structured-light stereo based depth cameras, such as the Kinect, are easy to use but are affected by significant amounts of noise.

High Quality Photometric Reconstruction using a Depth Camera

no code implementations CVPR 2014 Sk. Mohammadul Haque, Avishek Chatterjee, Venu Madhav Govindu

Firstly, instead of using an extra RGB camera, we use the infra-red (IR) camera of the depth camera system itself to directly obtain high resolution photometric information.
