Liu, Na Li, Zhiquan Guo","doi":"10.1109/ICICIP.2015.7388160","DOIUrl":"https://doi.org/10.1109/ICICIP.2015.7388160","url":null,"abstract":"Compressive tracking based on random channel Haar-like feature (RCCT) is proposed in this paper to improve tracking accuracy. Firstly, the color video frame is converted into grayscale image for tracking in real-time compressive tracking (CT), which may lose some information. Therefore, Haar-like features with random position and size are generated from three channels (RGB with random), represent the target better. What's more, it costs much time to detect new target round the position of the target in the current frame in the CT algorithm, and causes the target to drift when the speed of the target increases suddenly. Searching the new target in the vicinity of prediction target is proposed to reduce search time and to avoid missing the target. We have done experiments with large number of public data sets. Experimental results show that the RCCT algorithm reduces the average error of the target center compared with CT algorithm and other improved algorithms, and it performs favorably at the circumstances of the change of illumination and target position.","PeriodicalId":265426,"journal":{"name":"2015 Sixth International Conference on Intelligent Control and Information Processing (ICICIP)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127134835","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}

There is still no workable technology research and project implementation plan for PV power grid control about the problem of large-scale PV grid. First of all, the paper analyzed the basic principle of the solar cell power generation and introduced the equivalent circuit model of solar cell. The solar cell is a nonlinear power supply. Environmental temperature and light intensity have an important effect on its output power. To make the solar cell convert solar energy into electrical energy most efficiently, it needs to be maximum power point tracked(MPPT). Secondly, the paper studied on the control strategy for photovoltaic grid power generation system and established grid model with photovoltaic power plants, including a system circuit model and the active control model. Then in turn it analyzed automatic generation control(AGC) response of the system under the power fluctuations of new energy and under off-grid PV power plant emergency situations, the effect of photovoltaic active control mode on the grid frequency modulation(FM), the coordination control simulation of realtime scheduling and AGC. Finally it gave some research conclusions of active control strategy on the side of main station with large-scale photovoltaic grid.","PeriodicalId":265426,"journal":{"name":"2015 Sixth International Conference on Intelligent Control and Information Processing (ICICIP)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129153076","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}

Conventional researches on Russia population prediction are usually based on the standard cohort-component method. Such a method only allows for several factors (fertility, mortality and migration rates), and then leads to the lack of all-sidedness in the prediction results. With outstanding generalization ability, the feedforward neuronet is considered to be a more appropriate substitute. Besides, the back-propagation (BP) is of the most widely-used feedforward neuronet. As the conventional back-propagation neuronet has some inherent weaknesses, in this paper, two types of improved feedforward neuronet are constructed for the Russia population prediction. More specifically, a type of 3-layer power-activated neuronet (PAN) equipped with the BP algorithm (BP-PAN) and a type of 3-layer PAN equipped with the weights-and-structure-determination (WASD) algorithm (WASD-PAN) are built on the basis of 2013-year (from 1AD to 2013AD) historical population data for the Russia population prediction. By a lot of numerical experiments, the future declining trend of Russia population in the next decade is predicted with the highest possibility. In addition, via the Russia population prediction, the comparisons on the performance between the WASD neuronet and BP neuronet are conducted and summarized.","PeriodicalId":265426,"journal":{"name":"2015 Sixth International Conference on Intelligent Control and Information Processing (ICICIP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121748274","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}
