Thanks to the powerful ability of matrix computation provided by the OSSC (Open-source Software for Scientific Computation), we can establish a professional mathematical morphology toolbox. During the past years, our team has dedicated to a mathematical morphology toolbox on Scilab called SciMM toolbox. In this paper, we focus on the latest progress of SciMM. A new image segmentation function based on watershed transform is added to SciMM, which is coded with C as a dynamic link library that can be called by Scilab script through the interface function. The toolbox's folder hierarchy is then re-organized according to the newest guideline of making a Scilab toolbox.

Hybrid energy storage system with super capacitor is given priority to, supplemented by the batter provide adequate, stable and reliable energy guarantee for wind-pv hybrid streetlight system. With this technique a lighter and smaller energy storage system can be achieved which enhances the performance of wind-pv hybrid streetlight system. Super capacitor has drawn more and more attention on energy storage systems because of its advantages of high power density, high charging speed, long service life and small size, light weight and extremely high cycling capability. In this way the batteries can ensure only the average power and the super capacitors can ensure the power variations. When power is greatly change, super capacitors have energy storage buffer action. Storing capacity of super capacitor and variable current control function of parallel controller can reduce times of tiny battery charging and discharging, reduce the discharge depth, prolong the service life of the battery, which basiciy solved the problem of wind-pv hybrid streetlight system. The lifetime of the batteries, weight and volume of the HESS in wind-pv hybrid streetlight can thus been improved. The simulation results verified the validity of proposed control strategy.","PeriodicalId":197116,"journal":{"name":"2011 IEEE International Workshop on Open-source Software for Scientific Computation","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125294430","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}

When similar color existing in the background, traditional Camshift algorithm may fail, that is the target getting lost. To solve the problem, an improved Camshift algorithm is firstly proposed in this paper to reduce the influence of illumination interference. Besides, a method judging whether the target is lost is also proposed. Once the target is judged lost, the Speeded Up Robust Features (SURF) is utilized to find it again and the improved Camshift keeps on tracking the target continuously. SURF is invariant to scale, rotation and translation of images. We program in C++ based on OpenCV. The results prove that the proposed method is more robust than the traditional Camshift and give better tracking performance than some other improved methods.","PeriodicalId":197116,"journal":{"name":"2011 IEEE International Workshop on Open-source Software for Scientific Computation","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127652653","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}

Various commercial as well as open-source learning management systems are available today which are being used in educational institutions. These tools have introduced a new concept of teaching methodology which has huge benefits over traditional methods. In this paper, we describe six popular open-source tools and compare them in terms of learning model, functional features, modules, hardware and software requirements. Results of the comparison will help administrators and educators in adoption of learning management system that is most suitable for their needs, and also promote development and usage of open-source learning management systems.","PeriodicalId":197116,"journal":{"name":"2011 IEEE International Workshop on Open-source Software for Scientific Computation","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121834380","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}
