We present \(O(\log n)\) time SIMD hypercube algorithms for transforming binary images to linear quadtrees and vice versa, where \(n\) is the size of the images as well as the number of hypercube nodes. Our quadtree building algorithm, which generates the locational codes in preorder, is an improvem

## Abstract An algorithm of linear time complexity is presented to label connected components of a binary image by a quadtree. For a given node, the search for all adjacent nodes is carried out in __O__(1) (i.e., constant time complexity for the worst case) using our formerly presented algorithm in
Depending on different switching technologies, the multicast communication problem has been formulated as three different graph theoretical problems: the Steiner tree problem, the multicast tree problem, and the multicast path problem. Our efforts in this paper are to reduce the communication traffi
