A Method for Extracting Affine Invariant Local Features Using a Metric Tensor



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 metric tensor, an affine invariant smoothing filter and a set of affine invariant differential operators are constructed. Then, combining them a set of affine invariant feature extractions is constructed. Effectiveness of the proposed method is confirmed by experiments
