Solid walls are also very common in detention centres, for court yard delimitation. Other applications include sensors mounted on the external wall of a stone building, where detection of intrusions by wall climbing is needed. Until recently, the sensors used had to be mounted on the facade or the top of the wall using stand offs to perform properly. The sensor discussed in the article presents interesting characteristics that allow it to address the need for an invisible solid wall sensor. Indeed, ENCLOSURE uses a single cable concept that can be mounted directly on the wail. Using a local FM broadcast tower, the field surrounding the cable is not dense and distributes uniformly along the wail to prevent problems associated with rain or ice which are a problem to other sensors. For covert applications, the single leaky coaxial cable, can be embedded directly in the mortar of the wall during its construction, or grooved into an existing wall. Recently, ENCLOSURE has been successfully installed on different wall constructions. The latest results which include brick walls for detention centres, brick walls of an archaeological site and stone wall fences for a private VIP property are very encouraging. We present results of longer term beta testing for new wall mounted and fast deployable applications. Emphasis is placed on site particularities and the treatment of site impairments for those applications.","PeriodicalId":376576,"journal":{"name":"Proceedings The Institute of Electrical and Electronics Engineers. 29th Annual 1995 International Carnahan Conference on Security Technology","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124284098","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}

In most conventional schemes for the detection of moving objects, temporal differences of subsequent images from a video sequence are evaluated in a block based manner by so called change detection algorithms. These methods are based on the assumption that significant temporal changes of an image signal are caused by moving objects in the scene. However, as temporal changes of an image signal can as well be caused by many other sources (camera noise, varying illumination, small camera motion, trees in motion), such systems are afflicted with the dilemma of either causing many false alarms or failing to detect relevant events. To scope with this problem, the additional features texture and motion beyond temporal signal differences are extracted and evaluated in the new algorithm. Furthermore, these features are evaluated in an object-oriented instead of a block oriented fashion to increase the reliability of detection. The adaption of this method to normal fluctuations of the observed scene is performed by a time-recursive space-variant estimation of the temporal probability distributions of the different features (signal difference, texture and motion). Feature data which differ significantly from the estimated distributions are interpreted to be caused by moving objects.","PeriodicalId":376576,"journal":{"name":"Proceedings The Institute of Electrical and Electronics Engineers. 29th Annual 1995 International Carnahan Conference on Security Technology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115977140","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}
