Improved segmentation of a series of remote sensing images by using a fusion MRF model
Classifying segments and detection of changes in terrestrial
areas are important remote-sensing tasks. Some country areas are
scanned frequently (e.g. year-by-year) to spot relevant changes,
and several repositories contain multi-temporal image samples
for the same area in very different quality and details.
We propose a Multi-Layer Markovian adaptive fusion on
color images and similarity measure for the segmentation and
detection of changes in a series of remote sensing images. We
aim the problem of detecting details in rarely scanned remote
sensing areas, where trajectory analysis or direct comparison is
not applicable.
Our method applies unsupervised or partly supervised clustering
based on a cross-image featuring, followed by multilayer MRF
segmentation in the mixed dimensionality. On the base of the
fused segmentation, the clusters of the single layers are
trained by clusters of the mixed results. The improvement of
this (partly) unsupervised method has been validated on remotely
sensed image series
