Building Extraction of SAR Images Using Morphological Attribute Profiles
A building extraction method is proposed in this chapter used to deal with the special situation of SAR images processing. Morphological attribute profiles (APs) are the generalization of the recently proposed method morphological profiles (MPs). APs extract a multilevel characterization of an image by sequential application of morphological attribute filters. According to the type of the attributes considered in the morphological attribute transformation, different parametric features can be modeled. Here, the method proposed above is used for building extraction of SAR images. SVMs (Support vector machines) are used for classifications at last. The experimental analysis proved the usefulness of Aps in modeling the spatial information present in the image.
