Abstract Hierarchical representations are very convenient tools when working with images. Among them, the \alpha-tree is the basis of several powerful hierarchies used for various applications such as image simplifi- cation, object detection, or segmentation. However, it has been demon- strated that these tasks are very sensitive to the noise corrupting the image. While the quality of some \alpha-tree applications has been studied, including some with noisy images, the noise impact on the whole struc- ture has been little investigated.
