The application discloses a method and device for extracting skeletons of a brain CT (computerized tomography) image. The method comprises the steps of: carrying out grey mapping on pixel points of an original brain CT image to obtain a corresponding grey column diagram, and acquiring a first preset division threshold according to the grey column diagram; calculating a background pixel grey threshold according to the first preset division threshold, and removing background pixel points in the original brain CT image according to the background pixel grey threshold to obtain a pre-processed brain CT image; calculating a skeleton threshold based on the pre-processed brain CT image; and searching all pixel points of which the grey values are larger than or equal to the skeleton threshold in the pre-processed brain CT image, and extracting the image corresponding to the pixel points, wherein the image represents brain skeletons of the brain CT image. By applying the invention, the skeleton extraction error caused by carrying out empirical value setting on the skeleton threshold in advance is avoided; in addition, the method and device disclosed by the application can be used for extracting the image of brain skeletons within short time and do not bring negative influence to operation speed of integral algorithm.
