摘要
条形码信号的复原是数学物理反问题中的一种病态问题,正则化方法是解决病态问题最常用的方法。研究了信号盲复原的基本原理与方法,并将基于总变差的正则化方法应用到一维条码信号的复原问题中,仿真试验结果表明,该方法复原效果显著。
Restoration of barcode signal is an ill-posed problem in mathematical physical inverse problem;the most successful approach to which is regularization method.Basic theory and method of signal restoration was introduced.And an algorithm of total variation regularization was presented to one dimensional signal restoration.The simulation results showed that the effect of restoration was desirable and remarkable.
