Fast and Robust Normal Estimation for Sparse LiDAR Scans

no code implementations22 Apr 2024 Igor Bogoslavskyi, Konstantinos Zampogiannis, Raymond Phan

As most of the today's mechanical LiDAR sensors produce sparse data, estimating normals from a single scan in a robust manner poses difficulties.

Topology-Aware Non-Rigid Point Cloud Registration

no code implementations16 Nov 2018 Konstantinos Zampogiannis, Cornelia Fermuller, Yiannis Aloimonos

In this paper, we introduce a non-rigid registration pipeline for pairs of unorganized point clouds that may be topologically different.

Extracting Contact and Motion from Manipulation Videos

no code implementations13 Jul 2018 Konstantinos Zampogiannis, Kanishka Ganguly, Cornelia Fermuller, Yiannis Aloimonos

When we physically interact with our environment using our hands, we touch objects and force them to move: contact and motion are defining properties of manipulation.

Prediction of Manipulation Actions

no code implementations3 Oct 2016 Cornelia Fermüller, Fang Wang, Yezhou Yang, Konstantinos Zampogiannis, Yi Zhang, Francisco Barranco, Michael Pfeiffer

In psychophysical experiments, we evaluated human observers' skills in predicting actions from video sequences of different length, depicting the hand movement in the preparation and execution of actions before and after contact with the object.
