We are developing methods that can detect and recognize social interactions. Structures formed in our daily interactions play very important roles in understanding the social behavior, such as in office meetings, social gatherings, festivals and memorable events. In this work, we employ uncalibrated first person (or egocentric) views, face and body features analysis to detect and classify structures formed in interactions. Our focus is on real-world videos, like meetings in office environment, a trip to am amusement park or in scenarios where large number of people are involved. We proposed a search-based structure recovering method to reconstruct the complete social interaction with multiple .first-person views, where these views contributed to the multifaceted understanding of the social interaction (as shown in the figure below).
It populates the interaction group with multiple views, which are useful to present a complete interaction structure. We proposed a search-based reconstruction method, which are simpler than 3D reconstruction yet useful in capturing the social interaction spatial structure. To the best of our knowledge, this is the first time the multiple first-person view cameras are combined to analyze the social interaction spatial structure.
