| 摘 要： | 分段直接校正(PDS)算法是目前最常用的近红外光谱模型传递方法,但它在对整个谱区进行校正时,始终依赖大小不变的传递窗口.为了提高传递效果,本研究在PDS基础上提出了一种新的算法--小波多尺度分段直接校正法(WMPDS),用于混胺的近红外光谱模型传递,并详细讨论了模型的传递参数和传递结果.本算法首先对混胺的近红外光谱进行...

| Abstract: | Piecewise direct standardization(PDS) is the most popular method on near infrared analysis calibration transfer.One of the disadvantages of PDS is that the window widths are the same in the whole near infrared(NIR) spectral wavelengths as the window width is too large in some spectra region and too small in the others.A new calibration transfer method based on PDS was proposed to improve the calibrated results,the new method is wavelet multi-scale piecewise direct standardization(WMPDS).It was used for cali... |
