Abstract
Official abstract text for this publication.
To encode and compress a data array 30 , the data array 30 is first divided into a plurality of blocks 31 . A quadtree representation is then generated for each block 31 by initializing each leaf node of the quadtree to the value of the data element of the block 31 of the data array 30 that the leaf node corresponds to, and initializing each non-leaf node to the minimum value of its child nodes, and then subtracting from each node except the root node the value of its parent node. A set of data indicating the differences between respective parent and child node values in the quadtree representing the block of the data array is then generated and stored, together with a set of data representing a quadtree indicating the number of bits that have been used to signal the respective difference values.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of encoding an array of data elements for storage in a data processing system, the method comprising: generating at least one tree representation for representing the array of data elements, the tree being configured such that each leaf node of the tree represents a respective data element of the data array, and the data values for the nodes of the tree being set such that the data value that the tree indicates for the data element of the data array…
