Alice plans a trip to Vienna and she would like to find, in advance, areas of the city that are similar to her idea of Oxford Street. To model these preferences and action possibilities, we defined the following four features, which will later be used to define a similarity-distance to other identified shopping areas/settings: 1. 2. 3. 4. , subcategories of shops) n4 A Semantic Region Growing Algorithm: Extraction of Urban Settings 29 We denote by sðSÞ the total number of cells in a given segment/setting S.

3. What in image segmentation jargon is called a segment, is directly comparable to a setting: a set of contiguous cells satisfying the same description D. A setting S  C is a subset of the cell partition C and is called complete if it cannot be extended further with adjacent cells. 4. The segmentation of a map M according S to a description D produces a (possibly empty) set S of settings such that S2S S  C: A segmentation S ¼ fSg is called complete if it consists of only one setting such that S = C.
