LZW Decompression The LZW decompressor creates the same string table during decompression. It starts with the first 256 table entries initialized to single characters.
WebbWhile the Shannon-Fano tree is created from the root to the leaves, the Huffman algorithm works from leaves to the root in the opposite direction. Create a leaf node for each symbol and add it to frequency of occurrence. While there is more than one node in the queue: Remove the two nodes of lowest probability or frequency from the queue Webbü Procedure for shannon fano algorithm: A Shannon–Fano tree is built according to a specification designed to define an effective code table. The actual algorithm is simple: …
