In recent years, the application of fingerprint recognition technology has been covered many areas. Significant efforts are continuously being made in designing more efficient and more accurate fingerprint recognition algorithms both in academic and industrial environments. However, the fingerprint databases for the experiment are very limited. This paper describes a method for generating synthetic...
A novel digital image watermarking algorithm for copyright protection of digital products in digital library is proposed by using the generalized fuzzy c-means clustering (GFCM), Information fusion (InF), and discrete cosine transform (DCT). The presented approach can be applied to enhance robustness and security of copyright information in digital library. The original image blocks are classi"ed...
As a format for transmission and storage of multimedia data, MPEG2 transport stream is widely used in various Video-on-Demand systems. However, it cannot provide effective support for interactive operations. In order to support fast-forward and rewind operations, the I-frames of MPEG2 transport stream should be located rapidly. Traditional I-frame searching algorithms are not very efficient or accurate...
Industry repercussion effect is not only one of the foundations to measure the position of one industry in national economy system, but also a main basis for government to locate a leading industry. Through introducing the sensitivity degree coefficient and influencing power coefficient, the repercussion effect of Chinese petroleum industry has been measured. Besides, the strategic position of it...
Statistical soft wares facilitate data management and enhances the function of statistic. The statistical software SPSS (Statistical Package for the Social Science) 13.0 served in this study to exam the construct and develop a related scale of occupational stress of coal miners. 55 safety professionals with diverse education backgrounds in the safe supervision division of a state coal mine were recruited...
An approach to some statistical properties of chaotic attractors based on the cell model of chaotic attractor had been presented, we discusses some simulation issues about the method in the paper. It is helpful to apply the method to deeply study the structure of chaos attractors and understand the chaotic mechanism more properly.
