Image matching algorithm based on Delaunay triangulation and projective invariant

This paper proposed a new image matching method based on Delaunay triangulation and projective invariant in projective geometry .This new method firstly used triangulation function to compute the triangulation similarity of the triangulation in the matching images Delaunay triangulation ,then used the triangulation to execute rough matching. Secondly used projective invariant to remove the error matching in the result of rough matching And we realize this matching algorithm could match the photo images with part object moved. Experiments on real images demonstrate the good performance of this method.
