Proceedings of SPIE, 2010, Media Forensics and Security, vol. 7541, pp. 754113-754113-6 , University of California, Santa Barbara, Jan. 2010.
Abstract preview: Error correction codes of suitable redundancy are used for ensuring perfect data recovery in noisy channels. For iterative decoding based methods, the decoder needs to be initialized with proper confi ... more
