The Deciduous Tree Crown Segmentation Challenge

  Last update: 2026-08-26 Deciduous tree crown segmentation is widely recognized as a particularly challenging task. While various approaches for conifer crown delineation have proven successful, their transferability to deciduous forest stands remains limited. Accurate crown segmentation constitutes a critical prerequisite for assessing the vitality of individual deciduous trees based on spectral or structural metrics. In particular, in dense deciduous...
