A New Image Affine-invariant Region Detector and Descriptor

摘要

To solve the problems that exist in present affineinvariant region detection and description methods, a new affine-invariant region detector and descriptor are proposed in this paper. First, affine-invariant regions in an image are detected using a connectedregion based method. And then a vector composed of a group of affine invariant moments is adopted to descript the regions. Experiments show the effectiveness and robustness of the method. It is also very fast.
