Décomposition en ondelettes de maillages triangulaires 3D irrégulièrement subdivisés. Application à la compression

- Nous proposons un nouvel algorithme de subdivision qui permet la simplification des maillages triangulaires quelconques à l'aide de la transformée en ondelettes. Cet algorithme est appliqué à la compression sans pertes des maillages. Des résultats expérimentaux montrent l'efficacité de cette approche dans des représentations multirésolutions

The Mediterranean region under climate change

This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines
