Fuzzy directional enlacement landscapes

International audienceSpatial relations between objects represented in images are of high importance in various application domains related to pattern recognition and computer vision. By definition, most relations are vague, ambiguous and difficult to formalize precisely by humans. The issue of describing complex spatial configurations, where objects can be imbri-cated in each other, is addressed in this article. A novel spatial relation, called enlacement, is presented and designed using a directional fuzzy landscape approach. We propose a generic fuzzy model that allows to visualize and evaluate complex enlacement configurations between crisp objects, with directional granularity. The interest and the behavior of this approach is highlighted on several characteristic examples

Towards liminal balance: Unpacking the UK's urban canal space

This paper critically examines the liminal geographies of the United Kingdom's 7,000‐mile canal and river network, embodying a thread of complex intersections and interactions between water and land. Drawing on a study involving stakeholder interviews, group discussion with canal users, and observational walks in Manchester and London, the paper explores the concepts of liminal flux, scalar intersections, and deliminalisation. We first outline how the UK's urban canals are characterised by liminal flux over time and space, reflecting their dynamic geographies. Revealing the presence of critical intersections between liminality and scale, we then focus on the ongoing and everyday spatial and territorial entanglements between different canal and towpath users. Finally, we consider the challenge of deliminalisation, and an associated shift from liminality and in‐betweenness towards greater spatial fixity via neoliberal intervention and development. Our findings highlight the importance of preserving the unique characteristics of urban canals as liminal spaces, arguing that they provide recreational opportunities and contribute to urban wellbeing by providing opportunities for ‘transitory dwelling places’. Maintaining a liminal balance within urban canal environments is therefore crucial and requires careful curation. In turn, this notion of curating liminal balance has implications for other potential waterfront developments that offer a similar positive potential for hydrocitizenship and its fluid ambiguities of in‐betweenness. Moreover, it demonstrates the importance of a ‘lighter touch’ of redevelopment and governance in some parts of the urban environment to help preserve, or even enhance, citizen wellbeing
