abstract = "Per-point classification is a traditional method for remote
sensing data classification, and for radar data in particular.
Compared with optical data, the discriminative power of radar data
is quite limited, for most applications. A way of trying to
overcome these difficulties is to use Region-Based Classification
(RBC), also referred to as Geographical Object-Based Image
Analysis (GEOBIA). RBC methods first aggregate pixels into
homogeneous objects, or regions, using a segmentation procedure.
Moreover, segmentation is known to be an ill-conditioned problem
because it admits multiple solutions, and a small change in the
input image, or segmentation parameters, may lead to significant
changes in the image partitioning. In this context, this paper
proposes and evaluates novel approaches for SAR data
classification, which rely on specialized segmentations, and on
the combination of partial maps produced by classification
ensembles. Such approaches comprise a meta-methodology, in the
sense that they are independent from segmentation and
classification algorithms, and optimization procedures. Results
are shown that improve the classification accuracy from Kappa =
0.4 (baseline method) to a Kappa = 0.77 with the presented method.
Another test site presented an improvement from Kappa = 0.36 to a
maximum of 0.66 also with radar data.",
