Main objective of dual video watermarking is to achieve better compression rates, robustness against attacks and high security which has been rarely reported. In this paper, visible and invisible watermark is embedded in the video encoder during compression, resulting in an optimized compression/watermarking algorithm and system. Due to its lower complexity, Discrete Cosine Transform (DCT) watermarking...
The El Nino or Southern Oscillation is the outcome of the strong coupling and interactions between the Tropical Ocean and Atmosphere, which plays a major role in the development of global climatic system. In this study, a data set containing the Monthly Rainfall in Tamilnadu and a data set containing the Sea Surface Temperature of Nino 3.4 for 59 years (1950 - 2008) are used to model and analyse the...
