This paper presents an information hiding algorithm based on MSB, The numerical experiment illustrates that the algorithm has excellent robustness to Gaussian noise attack and clipping attack.
This paper presents a watermarking algorithm based on image segmentation, in order to improve the security of the watermark, take the DFT algorithm to deal with the watermark process, also analyze the robustness of the algorithm we taken though the experiments.
In the course of analyzing and deducing leak rate formula of fine leak test measurement of helium mass spectrometer, equivalent standard leak rate L is replaced with standard helium leak rate LHe . Helium gas exchange time constant zetaHe is cited, and the contents of typical gases inside hermetic cavity is calculated. It shows that after properly handling the measured leak rate deviation, a series...
