Item Open Access Automatic detection of compound structures by joint selection of region groups from a hierarchical segmentation(Institute of Electrical and Electronics Engineers, 2016) Akçay, H. G.; Aksoy, S.A challenging problem in remote sensing image analysis is the detection of heterogeneous compound structures such as different types of residential, industrial, and agricultural areas that are composed of spatial arrangements of simple primitive objects such as buildings and trees. We describe a generic method for the modeling and detection of compound structures that involve arrangements of an unknown number of primitives in large scenes. The modeling process starts with a single example structure, considers the primitive objects as random variables, builds a contextual model of their arrangements using a Markov random field, and learns the parameters of this model via sampling from the corresponding maximum entropy distribution. The detection task is formulated as the selection of multiple subsets of candidate regions from a hierarchical segmentation where each set of selected regions constitutes an instance of the example compound structure. The combinatorial selection problem is solved by the joint sampling of groups of regions by maximizing the likelihood of their individual appearances and relative spatial arrangements. Experiments using very high spatial resolution images show that the proposed method can effectively localize an unknown number of instances of different compound structures that cannot be detected by using spectral and shape features alone.Item Open Access Spectral returns of domesticity(SAGE, 2003) Baydar, G.This is a study of the link between the house and the city, based on a close reading of three historical statements from Western urban theory by Leone Batisti Alberti, Le Corbusier, and Paul Virilio. Sexualized metaphors of the house as the feminine, private realm and the city as the masculine, public realm proliferate in the modern period. However, rather than conforming to this conventional opposition, these three authors define the city in terms of the house. Their statements provide a curious link across temporal and geographical boundaries, with significant theoretical implications. In all three cases both the feminine figure and themes of loss and death underlie the desire to project the ideal city. In this paper I argue that these themes intertwine in complicated ways to assert urban identification in terms of a masculine desire of total control and mastery by silencing the feminine figure.
