Abstract
We have proposed a new spatio-temporal knowledge structure called 3D C-string to represent symbolic videos accompanying with the string generation and video reconstruction algorithms. In this paper, we extend the idea behind the similarity retrieval of images in 2D C+-string to 3D C-string. Our extended approach consists of two phases. First, we infer the spatial relation sequence and temporal relations for each pair of objects in a video. Second, we use the inferred relations to define various types of similarity measures and propose the similarity retrieval algorithm. By providing various types of similarity between videos, our proposed similarity retrieval algorithm has discrimination power about different criteria. Finally, some experiments are performed to show the efficiency of the proposed approach.
