Trees provide essential ecosystemic services (e.g. stocking carbon or locally regulating temperatures) and play an important role in the resilience to climate change, especially in urban areas. Quantifying these services in cities is difficult becaus

In this paper, we introduce a new method for the space-time registration of a growing plant that is based on matching the plant at different geometric scales. The proposed method starts with the creation of a topological skeleton of the plant at each

International audience; The above ground volume (AGV) measurement of a sampled tree is a fundamental input to provide predictions of forest, woodland and urban resources, but it is generally biased by country-specific merchantable thresholds. Terrest
