Strongly Convex Optimization for Joint Fractal Feature Estimation and Texture Segmentation
Barbara Pascal, Nelly Pustelnik, Patrice Abry
The present work investigates the segmentation of textures by formulating it as a strongly convex optimization problem, aiming to favor piecewise constancy of fractal features (loc…
Combining traffic counts and Bluetooth data for link-origin-destination matrix estimation in large urban networks: The Brisbane case study
Gabriel Michau, Nelly Pustelnik, Pierre Borgnat +3
Origin-Destination matrix estimation is a keystone for traffic representation and analysis. Traditionally estimated thanks to traffic counts, surveys and socio-economic models, rec…
Graph-based era segmentation of international financial integration
Cécile Bastidon, Antoine Parent, Pablo Jensen +2
