Abstract

This paper presents an approach to determine speed of camera motion in video sequences. The technique is based on the analysis of motion trajectories of the corners and interesting points in an image sequence. The spatio-temporal information of the feature points is a key significance in determining camera motion and speed value. The experimental results of speed analysis of camera panning, tilting, zooming, and the combination of panning and tilting are described. We also discuss the applications to help infer the higher-level semantic content and query information for the future video retrieval.
