Description: An optimized watermarking algorithm against print and scan based on discrete wavelet transform (DWT) is proposed. The algorithm divides the wavelet coefficients into three categories: low-frequency, medium-frequency and high-frequency, and loads watermarking information of different intensities according to the different resolutions of the three coefficients by the human visual system, which increases the robustness under the premise of ensuring the invisibility; at the same time, it adds the pretreatment process to the scanning image to improve the positive of the watermark information extraction. It is true. Experimental results show that the algorithm is robust to shear, noise and compression attacks.

Description: The cyclostationary signal is a special type of non-stationary signal whose statistical characteristics have a periodic variation with time. Due to the cyclical operation of the rotating machinery, the vibration signal has the characteristics of cyclostationary stability. Therefore, the cyclostationary analysis method can extract the hidden fault feature information that can not be obtained under the stationary assumption, which provides the possibility to effectively separate and identify the early weak fault features of the rotating machinery.
