In this research, we try to use the stereopsis technique to develop a simple 3-D image measurement system. First, we use a digital camera equipped with two lenses to take the stereo images. Moreover, the images can be transmitted to a computer by Wi-Fi in real time. Next, we calculate the 3-D coordinates of the measuring points using the triangulation technique. So it becomes possible to obtain various sizes. In order to detect feature points, such as a corner of the window, the techniques based on Hough transformation and the point matching method are proposed in this research.","PeriodicalId":359404,"journal":{"name":"2014 IEEE 6th International Conference on Awareness Science and Technology (iCAST)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126472616","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, these powerful tools have been misused by several CCTV operators. The governments and civil society are attempting to strike a balance between safety and privacy. Privacy filters can be used to help protect part of an image which included Personally Identifiable Information (PH). This paper presents a novel approach to improve the privacy protection in the CCTV displays. Our method uses context cues to determine the required privacy filtering level for each person in the image. We also present a systematic methodology to handle the context cues. We use a rules engine to generalise and facilitate the customisation of this system that by design should be specialized for operation in a given environment. In addition, we present a case study as a proof-of-concept whereby we have created an environment providing with high levels of privacy protection whilst allowing the required level of surveillance monitoring.","PeriodicalId":359404,"journal":{"name":"2014 IEEE 6th International Conference on Awareness Science and Technology (iCAST)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133423785","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}
