Detection of ruptures in spatial relationships in video sequences

Abstract :

The purpose of this work is to detect strong changes in spatial relationships between objects in video sequences, with a limited knowledge on the objects. First, a fuzzy representation of the objects is proposed based on low-level generic primitives. Furthermore, angle and distance histograms are used as examples to model the spatial relationships between two objects. Then, we estimate the distances between different angle or distance histograms during time. By analyzing the evolution of the spatial relationships during time, ruptures are detected in this evolution. Experimental results show that the proposed method can efficiently detect the ruptures in the spatial relationships, exploiting only low-level primitives. This constitutes a promising step towards event detection in videos, with few a priori models on the objects.
