    The 2nd International Conference on Intelligent Systems and Image Processing 2014, Nishinippon Institute of Technology, Kitakyushu, Japan, September 26-29, 2014We propose a new image processing-based finger touch position detection sensing method using a reflected image reflected on the screen. Using single camera by image processing to detect touch position has several significant advantages: (1) Installation of camera becomes easily (2) This system can reduce the failure rate to realize maintenance free operation. (2) This approach enables easy attachment and low-cost touch sensing. The problem when using single camera is impossible to detect the depth of the finger from capture image. In order to solve this problem, we use the reflected image of the finger appears on the screen. Detecting the fingertip and the reflected image on the screen effectively, we enable to detect touch position only using single camera. In this paper, we provide concrete method to extract fingertip and reflected image, implementation details, results of evaluation experiment, and outline future works

    This research proposes a Single Camera Finger Touch Position Detection System. Image processing based single camera figure touch position detection approach has several significant advantages: (1) No sensing devices need to be instrumented on the surface of the touch screen. (2) Minimum sensor construction can reduce the failure rate to realize maintenance free system. (3) This approach enables an easy installation and a low-cost touch sensing. The problem of using a single camera is how to detect the touch action and the position of the finger from a single view image. In order to solve this problem, we use the reflected fingertip image appears on the back of the screen. Detecting the fingertip and the reflected image on the screen effectively, we enable to detect touch position only using single camera. In this paper, we provide concrete method, algorithm, implement details, and several experimental results

    This study aimed to propose a triangulation by using a consumer 3D camera in order to measure a distance. In traditional method, error of distance measurement was large. The consumer 3D camera is different from a dedicated measurement stereo camera; the optical axes is installed so as to cross in front of lens several meters away (toe-in style), in order to give a sense of reality of human beingā€™s visual characteristic. We examine accuracy of proposed method by mesh data construction.The 2nd International Conference on Intelligent Systems and Image Processing 2014 (ICISIP2014), September 26-29, 2014, Nishinippon Institute of Technology, Kitakyushu, Japa

    New Vehicle Speed Measurement System with Image Processing

    This research proposes a new vehicle speed measuring system based on image processing technique. Generally, in order to detect the vehicle from image taken in dark circumstance, expensive high-performance camera is needed. However, this system needs only a cheap general camera, like digital camera or the camera mounted on smartphones. Thereby, this system uses as speed gun. By controlling the shutter speed of camera, a bright line which comes from the headlamp of a moving vehicle is appeared in the picture. Moreover, from even the image taken from the slant, the vehicle speed can be measured with a process of projective transformation. In this work, we developed an algorithm depend on this feature. Experiment result shows a reasonable measuring value.The 2nd International Conference on Intelligent Systems and Image Processing 2014 (ICISIP2014), September 26-29, 2014, Nishinippon Institute of Technology, Kitakyushu, Japa

    Construction of Multi Viewpoints Database by GA for AR

    Recently, as a useful application, the Augmented Reality (AR) has been widely adopted in mobile devices. In order to make the AR working smoothly on a low calculation ability smartphone, the high robustness and low calculation cost method is required. To realize such requirements, the Representative Image (RI) has been proposed. But, it does not guarantee the robustness in every case. In this study, an improved RI method using genetic algorithm is proposed. The numerous simulation result shows the proposed method is more robustness than the traditional one.The 3rd International Conference on Industrial Application Engineering 2015, March 28-31, 2015, Kitakyushu International Conference Center, Kitakyushu, Japa

    ā€˜Carrot and stickā€™ approach to housing demolition and relocation under flexible authoritarianism in urban China

    No full text
    Abstract In the context of the reconfigured state-society relation, Chinese statesā€™ modes of crisis management have profoundly transformed, featuring the stateā€™s greater efforts in reconciling the conflicts among the state machinery of capital accumulation, political stability maintenance and the increasingly diversified societal needs. However, how the local state performs specific missions accordingly in handling day-to-day conflicts on the ground remains under-examined. Accounting for the mundane yet nontrivial conflict resolving strategies featuring ā€˜carrot and stickā€™ approach, this article aims to fill this gap by examining the underlying logic, the operational mechanism, and the socioeconomic implications of flexible authoritarianism at the local level, based on an empirical investigation on how local state handles nail households in housing demolition and relocation in Dalian, China. We define ā€˜carrot and stickā€™ approach as a manifestation of flexible authoritarianism on the ground, which employs a variety of formal and informal strategies as well as administrative and market instruments to handle nail households-induced conflicts that are constitutive of the renewed state-society relation. This study reveals that the ā€˜carrot and stickā€™ approach under flexible authoritarianism has been rationalized as an efficient way for the local state to maintain political and social stability whilst sustaining the momentum of economic growth, thus widely employed in China. This research deepens our theoretical and empirical understanding of the dynamic state-society relation and flexible authoritarianism, and offers a detailed interpretation of why and how such hybrid and flexible ā€˜carrot and stickā€™ approach is rendered inevitable under the current politico-economic environment, power structure, legal and institutional configuration in urban China
