Having identical over-expansions of the image data, the ADAG offers greater potential for optimal basis identification, and thus better performance. 38, No. 2, March 1992. ASSP-34, No. 5, October 1986. 3, No. 3, May 1994. Notice that a separate wavelet packet tree is generated for each spatial segmentation.
Letters indicate redundant nodes.
Note, in these symbolic representations, it appears as if all children of a parent node are further spawned collectively using either frequency or spatial branching. In actual implementation, each child branches independently of the other children. This gives the trees a depth into the page, which is illustrated more completely in Figure 4 . Spatial segmentations indicated with black borders, frequency decompositions with white borders.
