| 摘要 |
The invention concerns a method for detecting and/or determining characteristics related to remarkable points in an image, characterised in that it consists in evaluating the local dip variability of a first point in the image relative to at least another point located in the proximity of said first point, by computing the local anisotropy on said point gradient field, said anisotropy being dependent on terms related to a dispersion of orientations and to the module of gradient vectors, and at least one of said terms is weighted. |
