Paper Abstract

This work discusses implementation issues of real-time video/image/signal processing applications on personal computers. We give a list of performance optimization guidelines and demonstrate some examples by optimizing our video watermark detection scheme. In many applications, watermarking technology must have (1) the ability to be implemented at low cost, (2) robustness against common image processing operations, and (3) resilience against purely malicious attacks. Many works, including ours, have demonstrated watermark robustness and invisibility. This work demonstrates that, after some performance optimizations, we can decode a 704 X 480 MPEG-2 video and detect the watermarks, both in software, and display the decoded video frames in real-time on an Intel PentiumR III 500 MHz system. Currently, there is only 10.5% overhead of the watermark detection over video decoding. The cost of our optimized implementation is 43% lower than that of the unoptimized version. The optimization techniques demonstrated in this work can be applied to other watermarking schemes and other video/image/signal processing applications.
