dahuffman is a pure Python module for Huffman encoding and decoding, commonly used for lossless data compression. The name of the module refers to the full name of the inventor of the Huffman code tree algorithm: David Albert Huffman (August 9, 1925 – October 7, 1999). ...
* * After the tree is built, a code table that maps a character to a binary * code is built from the tree, and used for encoding text. Decoding is done * by traversing the Huffman tree, as prescribed by the algorithm. * * Binary codes are represented by std::vector<bool>, which...

After encoding the size is reduced to 32 + 15 + 28 = 75. Decoding the code For decoding the code, we can take the code and traverse through the tree to find the character. Let 101 is to be decoded, we can traverse from the root as in the figure below. Decoding Huffman Coding ...
be the prefix of any other encoding bit pattern. This allows the encoded bitstream to be read bit by bit, and whenever a set of bits is encountered that represents a glyph, that glyph can be decoded. If the prefix-free constraint was not enforced, then such a decoding would be ...
Summarizing the research findings, it can be concluded that improving the encoding process can increase the capacity. Although the code book based scheme increases the encoding and decoding work, it reduces the amount of the transferred data and increases the capacity. So code book scheme is adopte...
