摘要
Abstract
Projection method based on target principal component of NIR spectra and Fisher criterion was established to improve leaf grading stability and redrying module credibility. Result showed that the application of PTF method can exactly describe classification of tobacco samples, and the projection values indicated the distance of different categories, the deviation of one category, and the intersection of two nearby categories, and hence the maximum of the ratio between the deviation of different categories and the deviation of one category was realized. The application of this method can facilitate tobacco leaf grading and redrying module designing.关键词
