Efficient shape recognition method using novel metric for complex polygonal shapes
Vesna Zeljković, Robert B. Vincelette, Marko D. Savic · 2006
We propose two new optimal and sub-optimal solution shape recognition algorithms using geometric calculations. Our algorithms are efficient and tolerate severe noise. They work for convex and concave polygons equally well. These algorithms are invariant under translation, rotation, change of scale and they are reasonably easy to compute.
