Adaptive partitioning of urban facades

Automatic Modeling of Urban Facades from Raw LiDAR Point Data

Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The key observation is that building facades often exhibit repetitions and regularities. We hereby formulate repetition detection as an energy optimization problem with a global ene...

Adaptive Partitioning

We present a new strategy for partitioning proofs, and use it to obtain new tightly secure encryption schemes. Specifically, we provide the following two conceptual contributions: • A new strategy for tight security reductions that leads to compact public keys and ciphertexts. • A relaxed definition of non-interactive proof systems for non-linear (“OR-type”) languages. Our definition is strong ...

Interactive Facades Analysis and Synthesis of Semi-Regular Facades

Urban facades regularly contain interesting variations due to allowed deformations of repeated elements (e.g., windows in different open or close positions) posing challenges to state-of-the-art facade analysis algorithms. We propose a semi-automatic framework to recover both repetition patterns of the elements and their individual deformation parameters to produce a factored facade representat...

Spatial Partitioning of Large Urban Road Networks

The rapid global migration of people towards urban areas is multiplying the traffic volume on urban road networks. As a result these networks are rapidly growing in size, in which different sub-networks exhibit distinctive traffic flow patterns. In this paper, we propose a scalable framework for traffic congestion-based spatial partitioning of large urban road networks. It aims to identify diff...
