Abstract

A possibility of reducing the number of informative features for multispectral phytogenous data by means of the factor analysis method
is shown in the article. For investigation there were used real reflection coefficients of maize, bristlegrass and ambrosia. Prior to usage of the
factor analysis it was performed the procedure to verify an initial set of data for conformity with distribution by the normal distribution law.
The factor analysis was conducted separately for three plants: maize, bristlegrass and ambrosia. Sizes of a new space were set for each plant,
and also there was given quality estimation of correlation between elements of a new and initial space of the data. Transfer to new features was executed provided that a level of informativeness was maintained at a level of 80% minimum in comparison with the initial set of data. For
each plant species the procedure of verification of the feature number choice correctness was performed by calculating of generalities. The
obtained results can be used to construct plant objects classifier.
