[The study of feature extraction of near-infrared spectroscopy with multi-scale edge extraction method].
The authors utilized a multi-scale edge extraction method to extract feature information of nearinfrared spectroscopy. Applying partial least-squares to charactcristic data obtained, the authors set up a linear mathematical model of the correlation between NIR spectrum and metronidazole contents. The result shows that the multi-scale extraction method can separate and extract feature information, and can be seen as an effective method of spectrum information extraction. The present study offers a new solution to the problems in nearinfrared spectroscopy technology.
