中文摘要：
对Vondrak滤波的准则函数进行了探讨,提出了一种新的评价标准,即用滤波值的均方根误差与平滑度的线性组合的平方根δ作为平滑因子质量好坏的评价标准。模拟算例证实了此评价标准的可行性。
英文摘要：
This paper studied the Vondrak filter and its criteria of functions.The thesis analyzed existing evaluation for the vondrak’s filter.The existing criteria for evaluation of Vondrak filter was cross correlation coefficient and root-mean-square error（RMSE）,which had some weak point in some place.A new criteria for evaluation was proposed that square root（δ） of the linear combination,which was the squre of root-mean-square error and the smoothness.The new criteria for evaluation was a quantitative index.The practicability and the advantage of the new criteria for evaluation has been demonstrated through simulated data.
