Provided are a human recognition apparatus and a human recognition method identifying a user based on a walking pattern. The human recognition apparatus includes a detecting unit detecting a vibration according to a user's walking, and outputting an electric signal, a pattern calculating unit acquiring a walker's walking pattern from the electric signal, and a user determining unit comparing the walking pattern with a previously measured reference data by user and identifying the user based on the comparison result. The human recognition apparatus and the human recognition method are robust against peripheral noise and can increase an acceptance rate through a simple structure and procedure by using the waling pattern, which is one-dimensional time information requiring no vast data throughput, as the user identification data.

A data transmission apparatus of an intelligent robot system and a method thereof are provided. The data transmission apparatus includes a vision processor collector, a communicating unit, and a controller. The vision processor collects images captured through a camera, and performs an image process on the collected image to minimize a quantity of information about unnecessary regions in the collected image. The communicating unit communicates with the robot server, transmits the processed image data from the vision processor to the robot server, and receives corresponding result data from the robot server. The controller controls the image process and the transmission of the processed image data in the vision processor, and a corresponding operation of the robot terminal performed according to result data received from the robot server.

Disclosed are an apparatus and a method for extracting an edge to be used for extracting a feature point of an object in an image. The present invention proposes an image edge extracting apparatus and method that remove noise in an input image, calculate a gradient of an image in a noise-removed image, measure magnitude of the gradient, extract an edge having a maximum thickness value, and then calculate a threshold using a ratio of the extracted edge, and detect a final edge robust against noise based on the threshold.

There are provided an apparatus and method for vision processing on a network based intelligent service robot system and a system using the same. A robot can move to a target object, avoiding obstacles without helps of a robot server interfaced with a robot terminal over network, by extracting/processing three-dimensional distance information of external objects, using a stereo camera, a low price image processing dedicated chip and an embedded processor. Therefore, the intelligent robot can travel and move using only a stereo camera image processing without other sensors, and further provides users with various functional services with low expense.
