This paper proposes techniques to query encrypted XML documents. Such a problem predominantly occurs in “Database as a Service” (DAS) architectures, where a client may outsour...
Local Binary Pattern (LBP) has been widely used in texture classification because of its simplicity and computational efficiency. Traditional LBP codes the sign of the local diffe...
Elevation maps are a widely used spatial data representation in geographical information systems (GIS). Paths on elevation maps can be characterized by profiles, which describe re...
