The biogas generator system put into practice has the deficiencies of poor stability, robustness and real-time, which has impacted the promotion and development of biogas power generation technology greatly. This paper designed a new monitoring model according to these deficiencies. This model established fault diagnosis subsystems according to the procedure of gas power generation, based on probability...
In this paper, a wavelet-based. watermarking scheme used to verify the contents of transmission grayscale images is proposed. By the property of discrete wavelet transform, we design two watermarks from the low-frequency band and embed the watermarks into the high-frequency bands. One watermark is used for detecting the intentional content modification and indicating the modified location, and anther...
Biometric watermarking refers to the incorporation of biometrics and watermarking technology. In this paper we proposed a novel biometrics watermarking scheme in the host as notice of legitimate. In the watermark embedding process, the wavelet coefficients of the host image are grouped into wavelet trees and each watermark bit is embedded using two trees. The trees are so quantized that they exhibit...
