Abstract
There is provided a method of processing an input data stream including compressed image data in which an extended tree, characterized by a plurality of words, is developed. Each word is associated with a token set and the words are corresponded with the token sets, respectively, by way of, for example, a look-up table. In practice, a sample word, representing a portion of the compressed image data, is sampled from the input data stream and matched with a selected one of the words from the tree to obtain the token set corresponding with the selected one of the words. The compressed image data portion is then processed in accordance with the obtained token set.
