| 2 | Vector morphological operators in HSV color space显示文摘In HSV color space,the current vector morphological operators have low capability to reduce color noise caused by hue and saturation in color image processing.Because they sort the color pixels according to the hierarchical ordering of V,S,H,which is against the equal principle of the three channels in color image processing.A novel vector ordering based on the combination of H,S and V is proposed in this paper,and the associated vector morphological erosion,dilation and composite filtering operators are defined.Compared with the popular vector morphological operators,experimental results show that the new operators can reduce the color noise effectively without any new color pixels while preserving the image details.And the filtered images have higher peak signal-to-noise ratio(PSNR) and lower mean absolute error(MSE). | LEI Tao WANG Yi FAN YangYu ZHAO Jiong | 2013 | Science China(Information Sciences)2013，56，1： | 8 |

| 7 | Reconstruction of harmonic signals based on bispectrum显示文摘A method for accurate reconstruction of the harmonic signals from bispectrum is presented. Based on the analysis of the measured harmonic signal, a sinusoid signal with Ophase, 1-amplitude and half of the fundamental frequency combines with the measured signal to form a combined signal, and then the bispectrum analysis is carried out to reconstruct the phase and the amplitude of the measured signal accurately. Without the zero-phase assumption of the fundamental component, using the new method eliminates the phase shifting between the calculated Fourier phase and the true Fourier phase in the existing signal retrieval methods based on bispectrum. The simulation results show the effectiveness of the new method. | FAN Yangyu SUN Jincai LI Pingan XU Jiadong (Northwestern Polytechnical University Xi’an 710072) SHANG Jiuhao (Northwest Institute of Light Industry Xian’yang 712081) | 2000 | Chinese Journal of Acoustics2000，19，1： | 0 |
| 8 | THE METHOD OF SEPARATING HARMONIC SIGNALS FROM MULTIPLICATIVE AND ADDITIVE NOISES显示文摘This paper focuses on the extraction of a harmonic signal from multiplicative and additive noises. A method is proposed in two stages: (1) to square the original discrete time series, which in- cludes both signals and noises, and form a new time series. By this means, the multiplicative noise is converted to additive noise; and (2) to filter out the noise by using existing noise removal schemes. With a large amount of simulation, experimental results demonstrated the efficiency and effective- ness of this newly developed method in terms of Signal-to-Noise Ratio (SNR) and other criteria. From the experiment, it is also found that: the two kinds of noises affect the SNR differently. In gen- eral, the SNR is not influenced by multiplicative Gaussian noise regardless of its variance. However, if both kinds of noise exist, the SNR decreases with the incensement of the Variance of Additive Noise to Multiplicative Noise Ratio (VAMNR). This analysis is also supported by simulation work. | Fan Yangyu Zhang Zhengwei Wei Xiaorong Zeng Li Wei Wei | 2007 | Journal of Electronics(China)2007，24，6： | 0 |
| 9 | Feature extraction of ship-radiated noise using higher-order spectrum显示文摘The features of the ship noises are analyzed by using the higher-order spectrum (HOS) after studying their distribution. The results show that the different ship noise has different ranges of the main frequency. The main frequencies of the first class ships are less than 120 Hz, while the second class ships drop in 130 Hz -- 320 Hz. The different relationship between w1 and w2 corresponds to different bispectrum graph. There are the same results in the trispectrum. The feature vector is consist of the wls which correspond to the maximum bispectrum B(wl, wl) and the maximum trispectrum B(wl, w1,wl) respectively, the al, w2 which correspond to the maximum bispectrum B(wl, w2). | FAN Yangyu SHANG Jiuhao (Northwest Institute of Light Industry Xian’yang 712081) SUN Jincai LI Pingan XU Jiadong (Northwestern Polytechnical University Xi’an 710072) | 2000 | Chinese Journal of Acoustics2000，19，2： | 0 |
| 10 | Feature extraction of ship radiated-noise by 1(1/2)-spectrum显示文摘The properties of 1(1/2)-spectrum are proved and the performances are an- alyzed. By means of the spectrum, the basic frequency component of the harmonic signals can be enhanced. Gaussian color noise and symetrical distribution noise can be canceled. And non-quadratic phase coupling harmonic components in harmonic signal can be reduced. The ship radiated-noise is analyzed and its 7 features are extracted by the spectrum. By means of B-P artificial neural network, three type ships are classified according to extracted features. The classification results about the three type ships A, B and C are 90%, 91.3% and 85.7%. respectively. | FAN Yangyu, TAO Baoqi, XIONG Ke, SHANG Jiuhao, SUN Jincai, LI Yaan (The key laboratory for smart materials and structures, Nanjing University of Aeronautics & Astronautics Nanjing 210016) (Northwest University of Light Industry Xianyang 712081) (Northwest | 2002 | Chinese Journal of Acoustics2002，21，2： | 0 |

| 12 | New chaos-based encryption scheme for digital sequence显示文摘To enhance the anti-breaking performance of privacy information, this article proposes a new encryption method utilizing the leaping peculiarity of the periodic orbits of chaos systems. This method maps the secret sequence to several chaos periodic orbits, and a short sequence obtained by evolving the system parameters of the periodic orbits in another nonlinear system will be the key to reconstruct these periodic orbits. In the decryption end, the shadowing method of chaos trajectory based on the modified Newton-Raphson algorithm is adopted to restore these system parameters. Through deciding which orbit each pair coordinate falls on, the original digital sequence can be decrypted. | Zhang Zhengwei Fan Yangyu Zeng Li | 2007 | Journal of Systems Engineering and Electronics2007，18，4： | 0 |
