| Abstract: | With some improvements to the traditional edge detection and segmentation method,We expanses these to a three-dimensional volume data.Because the hessian matrix has a strong edge effect,the maximum eigenvalue of the hessian matrix is extracted,and it has made some effect. |

| Keywords: | edge extraction region segmentation hessian matrix medical images |
