Representation of data using hierarchical data structures is commonly used in applications such as computer graphics, digital image processing, computer vision and techniques are being evolved for efficient representation of these data. Transforming bilevel images to linear quadtrees is a way of representing the high-volume data. In this paper, the preliminary investigation and results thus obtained for transforming binary images to linear quadtrees using Parallel Virtual Machine System Software are presented. Single Instruction Multiple Data hypercube algorithms implemented using PVM software was tested under DOS operating system on IBM compatible PCs. The quadtree algorithm generates locational codes in pre-order and generally runs in O(log n) time and this paper tested the feasibility of achieving this time for an SIMD machine
