Abstract: Provided is a system and method for preventing an animal being managed by a human from approaching a certain area using image recognition technology. This system includes an apparatus put on the animal, and a marker having either a preset color or a preset shape or both and installed in the certain area. The apparatus put on the animal includes a camera to capture a ground surface image of a movement path of the animal, a stimulus applying means to apply a stimulus to the animal, a memory to store an image of the marker, and a control unit, and operates the stimulus applying means to apply a stimulus to the animal when an image matched with the image of the marker stored in the memory is recognized in the image captured by the camera as the animal moves.

Abstract: As the advertisement market of a subway has emerged, a new subway advertisement system for displaying a video in a window of a moving train is suggested. The video quality in such a subway advertisement system is dependent on the accurate and rapid measurement of the speed of the train and achievement of the frame and horizontal pixel synchronization of the video to be represented. A sensor network of a cluster structure is provided that is effective to the subway advertisement system offering based on the network a high-speed/high precision speed measurement and the adaptive synchronization algorithm. Further, the video contents must be often renewed in the subway advertisement system and a speedy data downloading is essential. The tunnel video system suggests a method for improving the data speed through constructing a new structure of a data exclusive network in addition to the sensor network.
