%X Curve smoothing plays an important role in both Computer Aided Geometric Design and related manufacturing industries.In this paper,considering discrete digital curve is looked as non-stationary signal,a novel method of filtering discrete digital plane curves based on Bivariate Empirical Mode Decomposition(EMD) is presented.Firstly,separate the variables of the discrete plane curve,and parameterize them into two one-dimensional signals.Secondly,use the method of EMD to filter and remove the high-frequency no...
