ELLIPSDF: Joint Object Pose and Shape Optimization with a Bi-level Ellipsoid and Signed Distance Function Description

no code implementations ICCV 2021 Mo Shan, Qiaojun Feng, You-Yi Jau, Nikolay Atanasov

It is compact because it relies on a low-dimensional latent representation of implicit object shape, allowing onboard storage of large multi-category object maps.

Localization and Mapping using Instance-specific Mesh Models

no code implementations8 Mar 2021 Qiaojun Feng, Yue Meng, Mo Shan, Nikolay Atanasov

We show that the errors between projections of the mesh model and the observed keypoints and masks can be differentiated in order to obtain accurate instance-specific object shapes.

Constructing Effective Personalized Policies Using Counterfactual Inference from Biased Data Sets with Many Features

no code implementations23 Dec 2016 Onur Atan, William R. Zame, Qiaojun Feng, Mihaela van der Schaar

This paper proposes a novel approach for constructing effective personalized policies when the observed data lacks counter-factual information, is biased and possesses many features.
