Learning to Understand Body Language from Flight through Robust 3D Avatar Placing

Dragos Costea, Alina Marcu, Cristina Lazar +1

Perceiving human motion and intent at long range is a prerequisite for socially intelligent aerial robots, yet the data to learn it barely exists. We introduce Drones2BodyLanguage,…

Real-time body pose non-verbal communication with a consistency-based reliability measure

Alina Marcu, Dragos Costea, Cristina Lazar +1

Body movement communicates intent at distances and in conditions where neither the face, nor speech can be captured. We study the recognition of communicative intent from 2D body p…
