(29) 一般化微分スペクトル法の特性とNIRにおける応用
第22回近赤外フォーラム講演要旨集，pp.113-116，2006-11
To improve the performance of differential processing in spectroscopy, two types of extended derivatives are introduced; fractional derivative (FD) and fractional absolute derivative (FAD). It is shown that the FD provides us with new flexibility as a continuous derivative order, and the FAD exhibits stable positions of peaks for any derivative orders. The FD and FAD applied to NIR rice spectra are given and their properties are discussed. PLSR analysis on the FD spectra is also given and shows effectiveness of fractional derivative order on improving the performance of estimating constituents in rice.
