A modification of the linear quadtree [3], the threaded linear hierarchical quadtree (TLHQT), is proposed for the computation of geometric properties of binary images. Since most of the algorithms used in connection with computation of geometric properties require frequent exploration of adjacencies, a structure which keeps permanently in memory some adjacency links is introduced. In this paper, we present some results obtained by using the TLHQT for labeling connected components, evaluating
