The current security monitoring system for transformer substation has several disadvantages, such as wiring issues, high cost of installation and maintenance and poor mobility. In order to solve these problems, this article proposes a solution that is intelligent inductive security system based on wireless sensor networks. Among this system the microwave sensors act as inductive terminals and form...
Based on the good characteristics of dual-tree complex wavelet transform (DT-CWT), an improved digital watermarking algorithm is presented in the paper. The algorithm improves the embedding scheme by selecting the embedding channels and using the visual masking of HVS. In order to increase the robustness against common attacks such as JPEG, JPEG2000 compressions, different filtering attack etc., this...
