In the monocular vision system, it is too difficult to segment the foreground from background when their grayscale and color are similar. Compared with the grayscale and color, the scenery depth are less susceptible to external environment, if depth information can be got in stereo vision, it would be much easier to segment the foreground. Unfortunately, scenery accurate dense disparity map is often hard to get. In the paper, an optimizing method of calculating the dense disparity based on graph cut is used, and based on the dense disparity, the features of color and disparity are combined by graph cut to improve the accuracy of the image segmentation. The experimental results show that the method provides a better dense disparity map and also reduces the effect of light and strengthens the stability of segmentation by combining the features of color and disparity in graph cut optimization algorithm.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125772179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If the voltage is not a normal sinusoidal signal, the current waveform will be distorted, so the power factor is not controlled and the current with harmonics will contaminate power supply. A current control method based on impedance estimation is proposed to solve the problem. In this new method, voltage with harmonics is decomposed into Fourier series. Their fundamental component is extracted in order to be tracked and controlled. What's more, an impedance estimator calculating resistor and reactor in controller is used to compensate the error voltage, which is generated by harmonics, the measurement of time delay and parameters variation. So the system not only realizes high power factor, sinusoidal current and stable DC link voltage, but also meet the application demand of the capability of power regeneration to the power supply. The results of experiment show that the proposed method is effective and practicable.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A global sliding mode control approach is developed to provide a framework for ensuring the existence of a sliding mode throughout the entire response, and can force the system state to be within the state region in which the NN is used when the system goes out of NNs control. Based on the Lyapunov stability theory, the uniform ultimate boundedness of the following error is proved.

In this study, a novel time-frequency analysis method, namely the null space pursuit-Hilbert transform (NSP-HT), is introduced to detect and identify the power-quality disturbance. The proposed method is an operational combination of the null space pursuit algorithm (NSP) and the Hilbert transform (HT). It decomposes a signal into many components according to their characteristics with NSP, and gets their instantaneous frequency at the same time. Then HT is employed to detect the instantaneous amplitude of each component. In the case studies considered here, some simulation experiments, including harmonics, interharmonics, voltage sag and voltage signal with changing frequency and amplitude of harmonics, will be investigated by using the proposed analysis method.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134609324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
