Abstract-- We present an approach for classification of re-
motely sensed imagery using spatial information extracted from
multi-resolution approximations. The wavelet transform is used
to obtain multiple representations of an image at different reso-
lutions to capture different details inherently found in different
structures. Then, pixels at each resolution are grouped into con-
tiguous regions using clustering and mathematical morphology-
based segmentation algorithms. The resulting regions are mod-
eled using the statistical summaries of their spectral, textural and
shape properties. These models are used to cluster the regions,
and the cluster memberships assigned to each region in multiple
resolution levels are used to classify the corresponding pixels
into land cover/land use categories. Final classification is done
