The Raman spectroscopy technique is a powerful and non-invasive for molecular fingerprint detection which has been widely used in many areas, such as food safety, drug environmental testing. But signals can be easily corrupted by fluorescent background, therefore we presented baseline correction algorithm to suppress the background this paper. In algorithm, of signal was suppressed fitting curve called using cyclic approximation method. Instead traditional polynomial fitting, B-spline due...
Many spectra have a polynomial-like baseline. Iterative polynomial fitting is one of the most popular methods for baseline correction these spectra. However, estimated by iterative may substantial error when spectrum contains significantly strong peaks or located at endpoints. First, uses temporary from current to identify peak data points. If peaks, then substantially deviates true Some good points might be mistakenly identified as and are artificially re-assigned with low value. Second, if...
As one of the key steps for data preprocessing Raman spectra, baseline correction is an effective method to eliminate fluorescence interference. Traditional algorithms such as polynomial fitting and uniform B-spline are simple easy implement, but uncertain order internal knots limit their flexibility. In addition, results traditional often occur over under phenomena. Therefore, we propose a algorithm spectra based on median filtering un-uniform B-spline. Firstly, trough points spectral...
