Surveillance Video Key Frame Extraction Based on Motion Trajectory Analysis

Currently, efficient and accurate key frame extraction for massive videos remains a challenge, especially in surveillance applications. Motivated by this observation, a method for surveillance video key frame extraction based on motion trajectory analysis is proposed. The implement of the proposed method is illustrated in detail, and the subjective and objective performances are compared with the state-of-the-art method. Experimental results have demonstrated that the proposed method outperforms existing state-of-the-art method in terms of accuracy for key frame extraction while requiring a comparable or even less computation time.
