First, colors in the image are quantized to several representing classes in the HSI color space. And then the uniform surface uncertainty of every pixel is computed which will be used to generate the fuzzy image. Then seeds are detected and region growing is implemented to form the initial regions. A region merging algorithm base on the color information is used to merge the over-segmented regions. Utilized in natural image and texture image processing, the new method has got a good performance.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114373163","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}

An important problem in the field of intrusion detection is the management of alerts. This paper describes a realtime aggregation and correlation system named Alertclu. With the aid of similarity-based alert clustering analysing technology, Alertclu can improve the aggregation of intrusion detection system outputs and allow one to seamlessly incorporate additional information. In addition, Alertclu supports the operators by classifying alerts into true positives and false positives. The results of experiment show that the proposed system is able to reduce the numerous redundant alerts and effectively reduces the analyst operators' workload.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116015033","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}

However, as the positions of crowd usually change dynamically, computing the contagion process becomes a challenge. There exists a solution for a similar problem, the N-body problem, but it's too time consuming to be adapted in crowd simulation as it needs to calculate the reactions between every two objects. In order to solve this problem, we provided a fast adjacent test and contagion computing algorithm with GPU acceleration. Firstly individuals' affection fields were set and projected onto two dimensional ground and represented by squares of the same size; secondly the whole ground was divided into squares as the same size as those for the affection projection; thirdly, adjacent squares were tested to generate the nearer neighbors and the contagion results were calculated. All these steps were processed in parallel by GPU.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114679190","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}

However, overreliance on step-by-step route directions from these automated navigation systems may result in less consciously building spatial knowledge of the environment, which is critical to wayfinding. Also, GPS devices may divert people's attention from objects in the physical world to virtual representations on screen, and make people less engaged with the real environment. Consequently, when GPS device are out of access, malfunction, or simply give wrong directions, people may not be well prepared to react to unexpected environmental conditions and find alternative action plans. Such mental unreadiness may cause safety problems in emergency situations. In this paper, we discuss the importance of building spatial awareness in wayfinding activities, analyze GPS features and constraints, and propose the context-awareness design principles that may supplement the efficiency of GPS as well as keep people actively engaged in exploration.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124675462","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}

Based on detection method of weak square signal in strong noise with a chaotic oscillator, a public-key robust watermarking scheme is proposed. This scheme can show all details except the private key. After the watermarking scheme is described, the model feasibility experiment and anti-attack ability experiments are made and discussed. Experimental and discussion results show that the scheme is robust enough against attacks of the commonly used image processing methods. Also, experimental results show that the algorithm is robust to malicious attacks.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115307574","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}

Many are solved using some scripting engines but programmers must spend a lot of time designing and implementing them. The use of learning engines tends to ease the work of the programmer. Learning classifiers systems (LCS) mix learning and evolution to generate adaptive behaviours. The extension of LCS to a polymorphic structure simplifies the rule coding without sacrificing performances.
