Research On Digital Watermarks In The Sudstrate Management

Oil monitoring technology is one of industry in recent years the widespread adoption of technology monitoring and diagnostic equipment, It is through the analysis were used in the monitoring machinery lubricants (Or medium ) Changes and the performance of carrying particle, to obtain machines provide lubrication and Moli state information, Evaluation of the situation and forecast its machinery breakdown causes, types and parts of the technical.With computer networks and the rapid development of communications technology, and conduct monitoring of RMON remote diagnosis may become the direction and development. Since iron spectral characterization and diagnostic needs of national staff as a result of several decades of efforts to establish a typical piece of the spectrum Moli. One of the main methods of control and monitoring of iron spectral analysis needed Rail spectral Moli spectral piece of intellectual property protection issues and security issues unfolding in front of us.This paper aims at the copyright of particle sudstrate protection and safe problem. Particle sudstrate as a result of the use of iron range for surveillance and detection of oil, the quality of the pictures is high demand. With embedded digital watermarks in the spectral films, if algorithm design unreasonable may cause some distortion photographs. Moli analysis and makes no sense. Moli against the special requirements of the existing discrete cosine digital watermarks robustness of the algorithm, safety, offensive and anti-identity research, and integrating the digital signal processing technologies, to find out the relationship between them, based on discrete cosine of the current transformation of the digital watermark algorithm improvements.In this thesis, the use of model-based DCT Watson visual models of iron spectral Moli spectral films for watermarks embedded watermarks found that although the programme can meet not only good visibility, but in outline, the results are not satisfactory identification, can not meet the Moli TV films to be withdrawn contours of the digital processing special requests, particle sudstrate affected particle correctdiagnosis. So many experimental basis in the algorithm improvements in visibility as possible and do not meet the Watermark not affect contours of Moli brought digital TV films approach the premise change Watermark enhance regional and won a more satisfactory response to the special requirements of films Moli spectral digital watermarks embedded in the programme.
