Abstract
This letter presents advanced classification methods
for very high resolution images. Efficient multisource information,
both spectral and spatial, is exploited through the use of composite
kernels in support vector machines. Weighted summations of
kernels accounting for separate sources of spectral and spatial
information are analyzed and compared to classical approaches
such as pure spectral classification or stacked approaches using
all the features in a single vector. Model selection problems are
addressed, as well as the importance of the different kernels in the
weighted summation.
