Mathematical morphology multi-level analysis of trees patterns in savannas

In Earth remote sensing, observed landscapes can be decomposed by the superposition of objects of different sizes. The authors describe, characterize and separate those elements that make up an analysis process for those landscapes. In this paper, a method combining both the multiresolution analysis and mathematical morphology theories is proposed to perform this process. The suggested example deals with an image over Niger, and enables the separation between the hydrographic network, the herbaceous cover and bushes
