提出了一种迭代多项式拟合方法用于化学信号基线的估计。新方法通过将化学信号与多项式拟合的计算信号在迭代过程中进行比较来产生自动阈值。信号峰值在迭代过程中被连续地切掉，因此多项式拟合最终将给出基线的良好估计。利用毛细管电泳实验的模拟数据和真实的数据验证了该方法的可行性。(c)2005 Elsevier B.V保留所有权利。
An iterative polynomial fitting method is proposed for the estimate of the baseline of chemical signal. The new method generates automatic thresholds by comparing the chemical signal with the calculated signal from polynomial fitting in the iterative processes. The signal peaks are cut out consecutively in the iterative processes so the polynomial fitting will finally give a good estimation of the baseline. Simulated data and real data from capillary electrophoresis experiment are used to demonstrate the feasibility of the proposed method. (c) 2005 Elsevier B.V All rights reserved.
