Fast Watermarking of Traffic Images Secure Transmission in Effective Representation Mode

Abstract

Abstract:A static image secure transmission in effective representation mode for transportation systems was advanced based on fast watermarking theory. Firstly, the characteristics of image stream recognition in intelligent transportation system were analyzed and traffic image stream reorganization model was constructed. Then, according to effective representation mode, fast watermarking algorithms of image stream for intelligent transportation system were proposed, such as feature extraction-, compressive sensing-and sparse representation-based algorithms and detailed introduction of the first algorithm was given. Finally, referring to the evaluation criterion of digital watermarking and features of traffic static image, the performance of the above three algorithms are evaluated. The study shows that these three algorithms can satisfy different feature demands for traffic image secure transmission.
