The algorithm is based on principal component analysis of generalized Hebb adaptive algorithm in artificial neural network and to do adaptive quantitative coding for principal component coefficients according to the proportion of marginal or textural information of the watermark image. In addition, it adaptively adjusts the embedding depth according to the images features to ensure the invisibility of the watermark. By way of disparting and stochastic embedding into color image watermark, it increases the embedding robusticity of watermark. By utilizing block-concerned technique, it realizes public watermark image algorithm. It respectively applies in face-identifying watermark with abundant marginal information and figureprint watermark with rich textural information, and gains fine feedback.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.

The small dimensions, battery operation and inexpensive electronic components make this electrochemical detection system ideal for in situ or field measurements.

Losses (elastic, piezoelectric and dielectric losses) or hysteresis in piezoelectrics are discussed in detail. The relationships of three dissipation factors (correspondent to three losses mentioned above) and equivalent circuit parameters are derived from the hysteresis theory and the piezoelectric equations. It is approved that the dissipation factors are dependant on complex coefficients and can be obtained through measuring the equivalent circuit parameters experimentally. When loaded by increasing stress, the piezoelectric transducer is monitored and the equivalent circuit parameters are measured. Dissipation factor vs. stress curves are plotted. With the theory that losses are considered to consist of four portions: domain wall motion; fundamental lattice portion; microstructure portion and conductivity portion, phenomenology of loss variations with stress is explained.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.
