Characteristic Region Selection Methods for Three-dimensional Fluorescence Spectrometry
Based on combination of binary convex function discriminant theorem with clustering analysis
a new method of characteristic region selection for three-dimensional fluorescence spectrometry is proposed. By this method
the convex regions with valid spectral data are obtained.Experiment for detecting total organic carbon (TOC) in water and AFB1 in liquor are carried out. The experimental results show that the proposed method improves the accuracy of the regress model with increase of 6.17% and 4.97% respectively.
