The present invention provides a method and apparatus for appropriately performing the intra-cerebral hemorrhage lesion segmentation by determining a higher scale level image by means of a scale space filtering on an X-ray CT image of a head with the onset of intra-cerebral hemorrhage, determining the region of interest which corresponds to a contour of brain based on the higher scale level image, performing an unsupervised classification on the image in the region of interest of the X-ray CT image of the head, and recognizing the intra-cerebral hemorrhage lesion by means of an expert system from the result of the unsupervised classification.
