Abstract
In this paper the relationship between compression rate and classification
accuracy for hyperspectral images is studied. We construct several clas-
sification trees using CART and then, for various rates, we measure their
classification accuracy after the input image has been compressed.
We compare two kinds of classification trees: first, we construct one-
stage trees, which classify the input image using only a single classification
stage. Second, we construct multi-stage trees; these use a mixed class that
delays classification of problematic pixels for which the accuracy achieved
in the current stage is not enough. Then, for several compression rates,
we study the classification accuracy evolution of such trees when a lossy
compression method is applied to the input image
