Abstract
We study linear 1-D signal-flow graph methods to devise hierarchical bottom-up and top-down transformations. It is shoun that hierarchical data structures (e.g. quadtrees) can be obtained directly from line-scanned data. Hierarchical generation of certain other transform coefficients (e.g. WHT coefficients) is another topic discussed in this paper.
