    Research of the Fault Feature Extraction of Rolling Bearing based on Image Processing by Zhang Qiantu, Fang Liqing

    Published 2015-01-01
    “…The feature extraction is crucial for fault diagnosis,although the existing feature extraction methods in time domain,frequency domain and time-frequency domain are effective,it is also necessary to find new methods in other domain.On the basis of the characteristic of snow images generated by analyzing SDP(Symmetrized Dot Pattern)method,a feature extraction method based on image processing are put forward.Firstly,the original vibration signals are transformed into snow images in polar coordinate by SDP method.Then,the shape features of the snow images in different fault pattern of rolling bearing are extracted by using image processing technology,and the characteristic parameters are analyzed.Finally,BP network are created to realize fault pattern recognition.The experimental results show that this method is effective.…”

    Authentication-based double images fractal watermarking model of vector maps by SUN Jian-guo1, MEN Chao-guang1, MA Chun-guang1, LI Cheng-ming2

    Published 2009-01-01
    “…To realize the invasion identification and copyright authentication, a novel digital watermarking model for vector maps based on authentication was introduced.A double images fractal coding technology was proposed for the compound images, namely, the map owner’s fingerprint was taken as the domain blocks and the vector map was taken as range blocks.The control parameters of fractal similarity computation were defined as watermarking, which could be embedded into the properties file of the map.Experiments and analysis show that, besides providing services of copyright protection, the model improves the robustness and the owners’ authentication probability.…”
