Planer Shape Recognition based on Shape Subcenter Hausdorff Distance
基于子形心集Hausdorf 距离的平面形状识别新方法

Combined with shape-spccilic points and Hausdorff Distance,a new shape matching measurement based on the concept oI shape subcenters is given here.It is used for shape recognition under rigid transformations,brings about great improvements on precision.while decreases calculating cost very sharply. The test shows it's more effective and faster than any old method.
