Superpixel computation can be seen as a process of grouping similar pixels trying to preserve image boundaries. In this work, we propose a label propagation method guided by hierarchy of partitions in the context of the marked (supervised) segmentation problem. The main idea of the proposed method is to propagate labels on a tree modelling a hierarchical representation of the image. We propose several criteria to decide, in the case of a conflict, which of the competing labels must be propagated into a neighbor region of the tree. According to our experiments, the proposed method outperforms the baseline provided by the
