WebNov 20, 2011 · Encoding the header was done by using 0 and 1 to encode the structure of the tree (rather than the frequencies). A "0" denoted moving along the tree, a "1" denoted we were at a leaf node. This resulted in a sort of pre-order traversal of the tree encoding it uniquely. For example, a tree like ( ( (a b) c) (d e)) would be encoded as "0001 a 1 b ... Weba) Train four original Huffman trees from different sets of training data. An example for JPEG dc coefficient coding can be found in Fig. 8 in [1]. b) Perform tree mutation to create the whole Huffman tree space. The operation is illustrated in Fig. 1. c) Randomly select m different trees from the space, and number them from 0 to m 1 .
