This paper proposes a method for extracting local features which is invariant under affine transformations. This method is based on the metric tensor . Using the met ric tensor, an affine invariant smoothing filter and a set of affine invariant differential operator s are construc ted. Then, combining them a set of affine invariant feature extractions is constructed. Effectiveness of the proposed method is confirmed by experiments.
