A computer-implemented method of characterising points in a three-dimensional digital medical image comprises determining (100) third order derivatives of the image at one or more points. At each of the one or more points, one or more invariant or semi-invariant features that characterise the local geometry at the point is determined (102) using the third order derivatives. The invariant or semi-invariant measures can be used for the computer-aided detection of lesions, abnormalities and other anatomical structures of interest. |
