Abstract: An intelligent network system including a client unit and a server unit providing a service to the client unit, and a method and computer-readable medium controlling the same are disclosed. If the server unit copies a process that performs a service requested by the client unit into the client unit, and the server unit cannot provide the service any longer, the process is copied to another available server unit so that the service can be continuously provided. Also, if there is no available server unit, the client unit receives the service using the copy process pre-stored in the client unit itself. Therefore, although the network or the peripheral device is in the worst state, the client unit can stably receive the service.

Abstract: A robot system rapidly performs a motion based on a gesture recognized from a user and achieves a smooth interface with the user. The system receives a gesture input by a user, and sets a position of a first gesture as a reference position, if the gesture input by the user is recognized as the first gesture. The system also judges a moving direction of a second gesture from the reference position if the gesture input by the user is recognized as the second gesture. The system recognizes a command instructing a robot to perform a motion corresponding to the judged moving direction.

Abstract: Disclosed is an image processing apparatus, method and computer-readable medium of a robot which efficiently manage a moving image acquired by the robot and reinforce security to prevent image leakage. In order to restore an object region within an original image photographed by the robot, a low-resolution image is generated using object password information and the original image to generate image information, and the image information is transmitted to a server over a network. The server detects the object password information and the low-resolution information from the image information and restores a high-resolution object image using the object password information and the low-resolution image.

Abstract: Disclosed herein is a system which transmits an image using a lossless compression method in a robot to provide a service over a network and a method thereof. The network-based robot separates an image acquired by a stereo camera into various image formats and transmits the various image formats to a service server. The service server synthesizes the separated image formats to suit an image request such as face recognition, object recognition, navigation or monitoring to restore and provide an original image. When the network-based robot transmits the separated image formats to the server, the original image is transmitted using the lossless method to improve the performance of the server. Even when a service using a new image is added, separated images are transmitted with respect to the image format requested by this service to more flexibly cope with the service using the new image. Since channels are separated in order to receive lossless data, network gain is obtained.
