Abstract
We develop a method for fast in-place transform processing of pictorial data. The method is based on a radix-2 transformation scheme operating on dyadically indexed array elements (pixels). An interesting feature of the method is its close relationship to the Walsh-Hadamard transformation (UHT) in the sense that for each transform operation on the pixels there exists an equivalent transform operation on their UHT coefficients. The relationship to quadtree and pyramid data representation amounts to another asset of the procedure. Applications of the method in the field of pattern recognition and image processing are also discussed.
