    • The present invention provides a method for recognizing the location of an indoor robot utilizing an artificial landmark, a natural landmark, an encoder, and an inertial sensor. The indoor robot includes an image acquisition which acquires images; an image processing unit which processes the acquired images; a map generating unit which generates a map based on the result of processing the images; a location recognizing unit which determines the location of the robot based on the result of processing the images and the generated map; and a location fusion unit which fuses the information of the encoder and inertial sensor and the determined location. The present invention provides the method for recognizing the location of the indoor robot including a step which check whether a natural landmark or an artificial landmark exists in the inputted images; a step which removes the noise of the images which the existence of a natural landmark or an artificial landmark is checked; a step which extracts characteristic points of the natural landmark from the images; a step which extracts characteristic points from the inputted images; a step which performing a binary-coded algorithm based on the information of the extracted characteristic points; a step which compares the registered natural landmark and artificial landmark with the information of the performance of the binary-coded algorithm and matches the information; a step which corrects the location using a Kalman filter; and a step which fuses the corrected location and the information of the encoder and inertial sensor.

    • PURPOSE: A method and apparatus for segmenting a medical image are provided to reduce a system load for generating a 3D segmentation volume by an interaction with a user. CONSTITUTION: 2D location information of a pointer is extracted from a 2D slice medical image(S120). A 2D segmentation region including the location of the pointer is determined based on the slice medical image information relating to the location information of the pointer(S150). The determined segmentation region is displayed in the slice medical image(S160). The segmentation region is selected as a seed for the segmentation of the 3D volume image.
