It becomes more difficult at night video systems due to low contrast against the background. This paper is proposing a framework that detects object and tracks it at low contrast night surveillance video. A robust intensity statistics based detection method has been designed for processing low contrast frame and detect object structure from it. Based on successful detection, it tracks the object using Kalman filter algorithm.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124819925","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}

For this, we consider two cases. First case is that the map which includes ROI information is used at the start with the robot's position. Second one is that ROI is designated when pre-defined conditions are fulfilled with some sensing data. In this case, some dynamic changes of environment can be reported directly and an operator can take action with the situation change. Designated ROI will be presented in the operator's screen by the pre-defined visualization rules.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127442478","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 previous studies, it has shown that, the perturbation observer of sliding mode control with sliding perturbation observer (SMCSPO) can estimate the reaction force acting on the instrument tip. The perturbation is defined as the combination of the uncertainties and nonlinear terms where the major uncertainties arise from the reaction force. However in presence of external dynamics, the vertical instrument inside the body has some effects during operation. Therefore the reaction force estimated by SPO will be a combination of actual reaction force and external disturbances. It is necessary for the surgeon to measure the disturbance effects on the instrument during operation for the sake of safety. This paper studies about dynamic disturbances acting on the instrument using SMCSPO algorithm. A three DOF robot has formed with surgical instrument in RoboticsLab environment. Simulation has shown that SPO of SMCSPO can estimate the actual reaction force quite correctly when the surgical robot is fixed. However, it shows that SPO does not have satisfactory results when the instrument carrying robot's joint are free to move. It has seen that the estimated perturbation of each joint of robot has no relation with each other. Therefore measuring disturbances of the robot joints can be calculated using forward kinematics laws.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126238878","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}

It is composed of three main modules, a 1-DOF under-actuated hand module to assist with hand grasp motions, a 3-DOF exoskeleton-type parallel wrist mechanism for wrist power assistance, and a 6-DOF serial chain to assist with arbitrary movements of the operator's forearm. The system uses a pseudo-exoskeleton approach; accordingly, some problems caused by the inconsistency between the joint axes of the robot and the human operator can be minimized. In this paper, an overview of the second version of the robotic system is introduced. Furthermore, the operating capability of the proposed robot is observed in a demonstration of the robot performing several activities-of-daily-living (ADL) tasks, such as picking up a pen with a pinch grasp, gripping an object with a power grasp, and the brushing of teeth.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"312 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120911234","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}
