SNNS classification of hyperspectral data of extensively used agricultural areas|
Bogdan Zagajewski and Dawid Olesiuk
The goal of this paper is a presentation of
artificial neural networks for land cover classifications of the DAIS 7915 hyperspectral
data. The research area covers seminatural ecosystems of pastures and meadows and
extensively used agricultural areas of the Low Beskid Mountains (the northern Carpathian Mts.)
in southern Poland. Algorithms based on the SNNS classification (multilayer one-way
perceptron with backpropagation learning method) of 3 key polygons Biesnik S,
N and Wiatrowki using training sets of 60 and 40 original bands (after
geometric and atmospheric correction) and first 13 MNF channels in different
textural windows (1x1, 3x3, 5x5 and 7x7 pixels) were used. The results were compared
with the reference sets acquired from ground validation. The best accuracy (92.1%)
for the test set was achieved using 60 original bands with the 3x3 pixel subpattern size,
and for the training set – 93.9% for this architecture.
