A Method of Recognizing Shape Distorted and partially Occluded Workpieces

This paper presents an algorithm for recognizing workpieces whose boundariessuffer from significant distortions caused by scalling,rotation,and partial occlusion.At first,a method of boundary description is introduced,in which main featuresare invariant or insensitive to shape distortions,Then a recognition method based onthe subsegment maching technique is discussed.Finally,a series of experimentalresults show that the algorithm works well.
