Maple Species Identification Based On Hyperspectral Imaging Time Series

Abstract

The aim of the study was to identify Acer campestre L., A. negundo L., and A. saccharinum L. from time-series hyperspectral data. Maple leaves were subjected to Hyperspectral Imaging (HSI) in laboratory conditions every 7-10 days for two years. Random forest (RF), correlation analysis, principal component analysis (PCA), PCA-RF and Gini index were used to determine significant spectral bands for species classification. This paper demonstrates that maple species can be accurately classified during specific periods of the growing season with a success rate exceeding 90%. These periods can vary from year to year. Research has demonstrated that using seven spectral bands is adequate for classifying maple species, while using twenty spectral bands can maximize accuracy. The repeatability of the obtained results confirms their representativeness over time and when using different methods of data processing.
