Video Content Description Using Fuzzy Spatio-temporal Relations

One of the important aspects in digital video applications is spatial and temporal characteristic. A very little progress has been achieved on spatiotemporal modeling of video data. In this paper, we present a fuzzy spatio-temporal model for video content description that supports spatio-temporal queries. Fuzzy definitions and membership functions of temporal relations are given and second order fuzzy temporal relations are proposed. A model representation for the specification of fuzzy spatio-temporal relationships among objects in a video sequence is presented. Such representations are used for content-based retrieval processing. We also report the experimental results performed on video sequences from MPEG-7 video content archive. KEY WORDS Spatio-temporal modeling, spatio-temporal relations, content-based retrieval, video database, multimedia database.
