Résumé
In this paper, mixed spectral-structural kernel machines are proposed
for the classification of very-high resolution images. The simultaneous
use of multispectral and structural features (computed using morphological
filters) allows a significant increase in classification accuracy
of remote sensing images. Subsequently, weighted summation kernel
support vector machines are proposed and applied in order to take
into account the multiscale nature of the scene considered. Such
classifiers use the Mercer property of kernel matrices to compute
a new kernel matrix accounting simultaneously for two scale parameters.
Tests on a Zurich QuickBird image show the relevance of the proposed
method : using the mixed spectral-structural features, the classification
accuracy increases of about 5%, achieving a Kappa index of 0.97.
The multikernel approach proposed provide an overall accuracy of
98.90% with related Kappa index of 0.985.
