abstract = "Automatic oil detection systems have been developed to improve SAR
image interpretation, composed of four principal stages: a) image
pre-processing; b) dark spot detection; c) feature extraction,
and; d) oil and look-alike classification. The dark spot detection
is considered the main step in the processing chain: without the
geometry of the spots, the oil and look-alikes classification is
unfeasible. In this context, this work aimed to develop an
automatic procedure able to detect dark spots in SAR images, by
the integration of segmentation and pattern recognition
techniques. The results presented are continuity of the studies
carried on by Genovez (2010) and consider the tree last stages as
follow: a) features extraction, exploratory analyses and feature
selection; b) dark spot detection using data clustering, and; c)
validation of the proposed method. Considering that in the
scientific community there isnt a wide agreement about the
operational use of fully automatic methods, the development of an
intelligent hybrid system, including decision rules able to
conduct the images for one automatic or semi-automatic processing,
was an interesting approach. The potential of these rules to
improve the automation process was indicated. Nevertheless, more
samples to return more robust rules are recommended in order to be
widely applied to all SAR images acquired.",
