New Method of 2D Shape Representation and Edge Smoothing
新的二维形状描述方法与边界平滑*

There is put forward a new methods of 2D(two-dimensional) shape representation which stores the object borderline pixels coordinate value(x_i,y_i) into two arrays x=Xi];y=Yi] by the sequence of object borderline tracking result.It changes a 2D image problem into two single dimension arrays' problem.It lowers down the complexity of analysis.A series of processes about object borderline can be implemented such as smoothing,enhancement,corner detection etc.By operating on the two arrays.The representation of this method and its basic property are Introduced.And a concrete analysis has been done for the course of workpiece boundary smoothing based on this 2D shape representation by wavelet.
