Advancement in technology has complemented the increased complexity of state-of-the-art video coding standards by providing high-performance multimedia platforms. This has resulted in non-negligible computational reliability issues, especially with respect to soft errors. This paper motivates the dire need towards computationally Reliable Video Coding (ReVC) on modern hardware platforms. We highlight...
In order to overcome the seriously constrained storage and processing problem of a single node in wireless multimedia sensor networks (WMSNs), distributed Wyner-Ziv image compression algorithm is brought forward based on Wyner-Ziv. In this paper, the pixel domain Wyner-Ziv video coding scheme is adopted to achieve the distributed video codec system, the principle and performance of the system is analyzed...
In this paper, a novel gray-level image watermarking algorithm based on local feature region and Singular Value Decomposition (SVD) is presented for copyright protection. A new way which utilizes the Binary Coded Decimal (BCD) method and encodes the gray-level secret information into bit string is used. It employs the singular values of SVD to extract the most valuable features of the watermark image...
In this paper we present real-time system for embedding of digital watermark in images. The production and distribution of multimedia data in digital format, raises the intellectual property rights (IPR) protection problem, since the digital data can be easily copied without quality degradation. With digital watermarking, information containing origin, status, and/or destination of the data, can be...
